Course number: CHEM1411 Course title: GENERAL CHEMISTRY 1 Semester hours: 4 Foundational Component Area A. The course “focus[es] on describing, explaining, and predicting natural phenomena using the scientific method.” This course focuses on the utilization of the investigation of chemical phenomena and the utilization of these phenomena in the processes of the scientific method to make predictions about how matter will interact, how to use instruments to measure these interactions and how to utilize the information gained from these observations to reach logical conclusions and make predictions about further investigations. Laboratory experimentation follows the scientific method. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports B. The course “involve[s] the understanding of interactions among natural phenomena and implications of scientific principles on the physical world and on human experiences.” Chemistry is a physical science that explores matter, the structure and behavior of elements, the characteristics of compounds and reactions between substances. The interactions among the various chemical processes is fundamental to fundamental to the operation of the physical world and hence, since human experiences is directly related to these chemical processes (i.e. human physiology, and energy), a paradigm must exist between the physical world of chemistry and human experiences. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports Core Objectives A. Critical Thinking, Aspect 3: “Students will analyze information effectively.” This course is designed to correlate the chemistry lecture with the laboratory and is inquiry based to engender the use of the scientific method. Each segment compliments the other and requires that the student utilize the knowledge gained from one to the other requiring the use of creative thinking. Throughout the course, numerous assignments, demonstrations, chemistry problems and laboratory experiments illustrate how students must analyze information effectively. An example of this analysis of information can be observed in the laboratory experiment “Identification of an Unknown Compound”: Students are required to run several tests on known compounds, and also on an unknown compound, comparing results to identify the unknown compound. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports B. Critical Thinking, Aspect 4: “Students will evaluate information effectively.” Chemistry is a rigorous math intensive subject that requires analysis of data, synthesis of the information gathered and the evaluation of the information in the solving of problems presented from the process. This occurs in both lecture and laboratory settings. Throughout the course, numerous assignments, demonstrations, chemistry problems and laboratory experiments illustrate how students must evaluate information effectively. An example of this evaluation of information can be observed in he laboratory exercise “Density of Solids and Liquids”: Students must use the density formula, measured volumes and masses to calculate the density of an unknown solid and an unknown liquid. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports C. Critical Thinking, Aspect 5: “Students will synthesize information effectively.” Chemistry is a rigorous math intensive subject that requires analysis of data, synthesis of the information gathered and the evaluation of the information in the solving of problems presented from the process. This occurs in both lecture and laboratory settings. Throughout the course, numerous assignments, demonstrations, chemistry problems and laboratory experiments illustrate how students must evaluate information effectively. An example of this synthesis of information can be observed in the laboratory exercise “Determination of a Chemical Formula:” Students will conduct an experimental procedure to separate a compound into its elements to determine the formula of the compound. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports D. Communication, Aspect 1: “Students will demonstrate effective development, interpretation, and expressions of ideas through written communication.” The course is math intensive and requires analysis of data, synthesis of the information gathered and the evaluation of the information in the solving of problems presented from the process. Students must effective develop, interpret, and express their findings in both lecture and laboratory settings through written communication. Homework assignments, test questions, and laboratory reports are some of the ways this is evaluated . The chemistry laboratory requires that students work together in the development of the appropriate protocol. The information developed in the laboratory requires that this information is then interpreted and reported in written and/ or visual communication. Because of the laboratory experience, students learn to share and cooperate in the expression of laboratory results see laboratory exercise “Theoretical Yield”: Students will determine the percent yield from a reaction, using calculated values for expected yield, and careful procedures to achieve the maximum actual yield. Documentation in the lab notebook will support the reasons behind the selected procedure. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports E. Communication, Aspect 3: “Students will demonstrate effective development, interpretation, and expressions of ideas through visual communication.” In the lecture and laboratory portion of this course students are required to effectively develop, interpret, and express their ideas and findings through visual communication. Lecture and laboratory assignments, homework, lab experiments and exam questions require that students work together in the development of the appropriate protocol. The information developed in the lecture/laboratory requires that this information is then interpreted and reported in written and/ or visual communication. Because of the laboratory experience, students learn to share and cooperate in the expression of laboratory results see “Geometric Structure” Students will construct molecular models representing six different geometric shapes, and analyze the models to determine polarity. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports F. Empirical and Quantitative Skills, Aspect 1: “Students will demonstrate effective manipulation of numerical data or observable facts” The course is math intensive and requires analysis of data, synthesis of the information gathered and the evaluation of the information in the solving of problems presented from the process. The chemistry course requires that students follow strict protocol and gather numerical data and then perform the appropriate analysis of that data and reach reasonable scientific conclusions based on that data. See “Titration and Neutralization” Students will use the color change at the end point of the titration to determine the molarity of an unknown concentration of acid. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports G. Empirical and Quantitative Skills, Aspect 2: “Students will demonstrate effective analysis of numerical data or observable facts” The course is math intensive and requires analysis of data, synthesis of the information gathered and the evaluation of the information in the solving of problems presented from the process. The chemistry course requires that students follow strict protocol and gather numerical data and then perform the appropriate analysis of that data and reach reasonable scientific conclusions based on that data.

The chemistry course requires that students follow strict protocol and gather numerical data and then perform the appropriate analysis of that data and reach reasonable scientific conclusions based on that data. See “Calorimetry/Specific Heat” Students will measure and record heat transfer between a liquid and a metal solid and calculate the molar mass of the solid to identify the metal. Assessment: Laboratory and Lecture exams, Homework Assignments, laboratory reports I. Teamwork: “Students will demonstrate the ability to consider different points of view and to work effectively with others to support shared purpose or goal.” The lecture and the laboratory portion of the course utilizes a collaborative learning environment. This is accomplished by breaking the students into small groups and those small groups working together to accomplish a shared goal. This occurs as students work on assigned questions or problems in lecture and lab. See laboratory exercise “Boyle’s Law” students will use the properties of a gas to observe pressure and volume changes and how one affects the other. This experiment requires one student to manipulate the gas syringe while the other records the changes occurring. The laboratory setting requires that the students work effectively with others in the pursuit of a common goal.

A core curriculum should offer student the opportunity to master both general methods of analyzing printed materials and specific methods for analyzing the subject matter of individual disciplines. WRITING – Competency in writing is the ability to produce clear, correct, and coherent prose adapted to purpose, occasion, and audience. Although correct grammar, spelling, and punctuation are each a sine qua non in any composition, they do not automatically ensure that the composition itself makes sense or that the writer has much of anything to say. Students need to be familiar with the writing process including how to discover a topic and how to develop and organize it, how to phrase it effectively for their audience. These abilities can be acquired only through practice and reflection. SPEAKING – Competence in speaking is the ability to communicate orally in clear, coherent, and persuasive language appropriate to purpose, occasion, and audience. Developing this competency includes acquiring poise and developing control of the language through experience in making presentations to small groups, to large groups, and through the media. LISTENING – Listening at the college level means the ability to analyze and interpret various forms of spoken communication. CRITICAL THINKING – Critical thinking embraces methods for applying both qualitative and quantitative skills analytically and creatively to subject matter in order to evaluate arguments and to construct alternative strategies. Problem solving is one of the applications of critical thinking, used to address an identified task. COMPUTER LITERACY – Computer literacy at the college level means the ability to use computer-based technology in communicating, solving problems, and acquiring information. Core-educated students should have an understanding of the limits, problems, and possibilities associated with the use of technology, and should have the tools necessary to evaluate and learn new technologies as they become available.

THEORETICAL AND PERCENT YIELD OF A CHEMICAL REACTION INTRODUCTION When the two elements antimony and iodine are heated in contact with one another, they react to from antimony (III) iodide. 2Sb(s) + 3I2(s) 2SbI3(s) The coefficients in this equation show that two moles of Sb (243.6 g) react with exactly three moles of I2 (761.4 g) to form two moles of SbI3 (1005.0 g). Put another way, the maximum quantity of SbI3 that can be obtained under these conditions, assuming the reaction goes to completion and no product is lost, is 1005.0 g. The quantity is referred to as the theoretical yield of SbI3. Ordinarily, in the laboratory, reactants are not mixed in exactly the ratio required for reaction. Instead an excess of one reactant, usually the cheaper one, is used. For example, 3.00 mol of Sb could be mixed with 3.00 mol of I2. In that case, after the reaction is over, 1.00 mol of Sb remains un-reacted. The 1.0 mol excess Sb is equal to the original 3.00 mol Sb minus the 2.00 mol Sb consumed. The 3.00 mol of I2 should be completely consumed in forming the 2.00 mol of SbI3. After the reaction is over, the solid obtained would be a mixture of product, 2.00 mol of SbI3 (1005.0 g), together with 1.00 mol of unreacted Sb (121.8 g). In situations such as this, a distinction is made between the reactant in excess (Sb) and the other reactant (I2), called the limiting reactant. The amount of product formed is determined (limited) by the amount of limiting reactant. With 3.00 mol of I2, only 2.00 mol of SbI3 is obtained, regardless of how much excess of Sb is used. Under these conditions, the theoretical yield of product is the amount produced if the limiting reactant is completely consumed. In the case just cited, the theoretical yield of SbI3 is 2.00 mol, the amount formed from the limiting reactant, I2. Often you will be given the amounts of two different reactants and asked to determine which is the limiting reactant and to calculate the theoretical yield of product. To do this, it helps to follow a systematic, three-step procedure: 1. Calculate the amount of product that would be formed if the first reactant were completely consumed. 2. Repeat this calculation for the second reactant: that is, calculate how much product would be formed if all of that reactant were consumed. 3. Choose the smaller of the two amounts calculated in (1) and (2). This is the theoretical yield of product; the reactant that produces the smaller is the limiting reactant. The other reactant is in excess; only part of it is consumed. EXPERIMENTAL PROCEDURE: 1. Accurately weigh three evaporating dishes and record their weights in the data table. In evaporating dish #1 NO MORE THAN 0.1 grams of magnesium, and NO MORE THAN 0.30 grams of magnesium to evaporating dish #2. Set dish #3 aside for now. 2. Add exactly 15 mL of 1.0 M HCl to each of the evaporating dishes and allow the reaction to proceed to completion. (Either all of the magnesium is consumed or all of the HCl is consumed.) 3. After the reactions are complete, carefully decant the liquid from the dish in which some magnesium remains into evaporating dish #3. Throw the excess magnesium in the trash. 4. Place each evaporating dish on a hot plate and evaporate to dryness. This has to be done carefully since the melting point of MgCl2 is rather low and if heated at a high temperature it will begin to decompose. 5. Allow the evaporating dishes to cool and weigh the dish and its contents. 6. Perform the calculations as directed by your instructor.
