Compound Notes

P Practice-
.
copy the following vocabulary words in your journal
•A compound-is made from two or more elements that are
chemically combined and can not be separated by physical
means into other substances. A compound has different
properties than the original elements that formed it.
•A chemical formula -is a combination of chemical symbols
showing the atoms of which a substance is made and their
proportions.
•A physical change -when substances undergo a change
without changing into another substance.
•A chemical change - when substances
undergo a change and become a new or
different substance.
P Practice-
•A subscript is a number written just below the line that
shows how many atoms of an element
are present in the formula.
•A molecule is the smallest particle of a
compound that can exist on its own and
keep its properties.
•A precipitate is a new substance produced as a result of a
chemical change (solid).
.
copy the following vocabulary words in your journal
P Practice- copy the following words in your journal.
 Compounds are formed when atoms
of different elements are combined.
 When the elements are combined
their identities change.
 Water is formed from hydrogen and
oxygen.
 Both elements are gases.
 When combined they turn to a liquid.
 Hence their identities change.
P Practice- copy the following words in your journal.
Analogy:
 Think of elements as letters of the alphabet and
compounds as words formed by combining the
letters.
 We can spell all of the English words with just 26
letters.
 We can form millions of compounds with just 109
elements.
 Ex: Sodium(Na) + Chlorine(CI) = Salt(NaCI)
P Practice- copy the following notes in your journal.
 What type of change occurs when forming
compounds?
 Chemical changes
 Do the characteristics of an element
change when combined with another?
 Yes, the change occurs on a molecular level.
 What happens when 2 or more elements
combine and their properties change?
 A compound is formed
P Practice- copy the T-chart in your notebook.

P Practice- Write each of the following statements
where they belong.
A. Found in Earth’s atmosphere.
B. Needed for humans to survive.
C. Made from more than one element.
D. Made of one pure substance.
E. Can be broken down into simpler substances.
F. Are pure substances.
G. Make up substances we use everyday.
H. Can be written using subscripts.
I. Can be found on the Periodic Table.

P Practice• Number your paper 1-10.
• You will watch as the teacher performs
difference changes and take notes on
what is occurring.
• You must make two observations for
each change.
• You will then decide if each is a
physical or chemical change.

S Starter: Write the question.
How many TOTAL atoms are found in the
following chemical formulas?
1. NH3
2. H2SO4
Compare the formulas below. What
makes them different?
3.H2O  H2O2 

P Practice
 Students will draw the lab setup in journal
and write observations and predictions
about what the lab could be demonstrating.
 REMEMBER: Even though some liquids
look similar, they can have very different
properties.
Please be careful with both substances, do not
taste or touch either substance over the next
two days.
P Practice
 I will explain what we are going to do in this
upcoming lab.
 It is your job to work with your group and
create the problem, hypothesis, materials list,
procedure, observations/data, results and
conclusion for this lab. (Today you will stop at
procedure.)
 Be specific in your instructions. (Pretend
someone has never done a lab before.)
 Be sure to include safety procedures.
 Use complete sentences and thoughts.
 Start at the very beginning
and work to the end.
P Practice
*HINT* PLEASE WRITE IN JOURNAL.
 Hydrogen peroxide is used as an antiseptic
to wash cuts. One characteristic of
hydrogen peroxide is that it will produce
bubbles when applied to a wound. Water
will not. The formation of bubbles is one
sign that a chemical reaction has taken
place.
Apply & Connect
1. What is the difference between water and
hydrogen peroxide on an atomic level?
2. Why would we do a lab with two substances
that look exactly the same? What does this
teach us?
