Chapter 8: Quantities in Chemical Reactions

Question 1

Explain the concept of stoichiometry.

Answer 1

study of quantitative relationships between reactants and products in chemical reactions

Question 2

Interpret a balanced chemical equation in “mole terminology.” For example, the equation
4 2 2 2CH + 2O 6 CO + 2H O, means that one mole of methane molecules reacts with two moles of oxygen molecules to produce one mole of carbon dioxide molecules and two moles of water molecules

Answer 2

Moles are determined by the coefficients
