Stoichiometry

Front

What are mole ratios?

Back

Mole ratios are the ratios of moles of one substance to moles of another substance in a balanced chemical equation.

Front

Where are mole ratios obtained from?

Back

Mole ratios are obtained from the balanced chemical equation.

Front

How do you balance a chemical reaction?

Back

To balance a chemical reaction, adjust the coefficients in front of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is the molar mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

When do I use molar mass in stoichiometry?

Back

You use molar mass when converting between grams and moles in stoichiometric calculations.

Front

How many steps are needed to convert moles given to moles unknown?

Back

It takes 1 step to convert moles given to moles unknown using mole ratios.

Front

How many steps are needed to convert grams to grams?

Back

It takes 3 steps to convert grams to grams: grams to moles of the first substance, mole ratio to moles of the second substance, and then moles to grams of the second substance.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, representing the conservation of mass.

Front

What is the significance of coefficients in a balanced equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction.

Front

What is the first step in stoichiometric calculations?

Back

The first step is to write a balanced chemical equation for the reaction.
