Test on Stoichiometry Ch 11

2. Stoichiometry is based on the law of conservation of mass? T?F

True

In any chemical equation, the mass of the products is equal to to the mass of reactants T/F

False

4. The coefficients in a chemical equation represent not only the number of individual particles but also the number of moles of particles? T/F

True

5. The mass of each reactant and product is related to its coefficient in the balanced chemical equation for the reaction by its molar mass.

True

Balanced chemical equations can be interpreted in terms of what?

moles, mass, and representative particles (atoms, molecules, formula units)

The law of conservation of mass…

applies to all chemical reactions

What are mole ratios derived from?

coefficient of a balance equation

All Stoichiometric calculations begin with ….

a balanced chemical equation

Why are stoichiometric calculations used to predict?

the amounts of reactants used and products formed in specific reactions

The amount of product formed depends on the?

limiting reactant

The actual yield is the amount of product produced and must be obtained through

experimentation
