What is Stoichiometry?
Objectives:
6.0 Solve stoichiometric problems involving relationships among the number of
particles, moles, and masses of reactants and products in a chemical reaction
6.3 Identifying the nomenclature of ionic compounds, binary compounds, and
acids
6.4 Classifying chemical reactions as composition, decomposition, single
replacement, or double replacement
Other AOD C.6.1 Define stoichiometry, reactants, and products.
Other AOD C.6.2 Explain the law of conservation of mass.
Other AOD C.6.3 Explain the concept of mole in terms of Avogadro's number.
Stoichiometry
• Def.: the quantitative study of relationships
between amounts of reactants used and
products formed in a chemical reaction
• Let’s think for a moment. If I hand you a
dozen chocolate chips, can you make a dozen
chocolate chip cookies?
• Well, every chemical equation is just a recipe!
Let’s Review!
• Iron + oxygen react to produce iron (III) oxide.
1. Write AND BALANCE the chemical equation.
ANSWER: 4 Fe(s) + 3O2(g)→ 2Fe2O3(s)
2. What type of reaction is this?
3. How many moles of each compound are
represented?
4. How many grams of each compound are
represented?
Review, continued…..
• Aluminum + bromine react to produce
aluminum bromide
1. Write AND BALANCE the chemical equation.
ANSWER: 2Al(s) + 3Br2(l)→ 2AlBr3(s)
2. What type of reaction is this?
3. How many moles of each compound are
represented?
4. How many grams of each compound are
represented?
