CHER3S Chemical Reactions Part 1 (Theory)

The mole is defined as:

6.022 × 10^{23} representative particles of a substance

Which statement best describes molar mass?

The mass of 1 mole of a substance

When converting from grams to moles, which of the following is always used?

Molar mass

In a balanced chemical equation, the coefficients represent:

The ratio of moles of reactants and products

Stoichiometry allows chemists to:

Determine the amount of product formed from given reactants

The law that stoichiometry is based on is:

Law of Conservation of Mass

The limiting reactant is:

The reactant that determines the amount of product formed

When a reaction stops, it is because:

The limiting reactant has been completely used up

If you double the amount of limiting reactant while keeping the other constant, the amount of product formed will:

Double

When determining the limiting reactant, it is most accurate to compare:

Moles of each reactant
