What is Stoichiometry?

Back

Stoichiometry is the branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the conservation of mass.

What is a mole in chemistry?

Back

A mole is a unit of measurement used to express amounts of a chemical substance, defined as exactly 6.022 x 10²³ particles (atoms, molecules, etc.).

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced in a chemical reaction based on the stoichiometric calculations.

Front

What is the actual yield?

Back

The actual yield is the measured amount of a product obtained from a chemical reaction.

Front

What is percent yield?

Back

Percent yield is a measure of the efficiency of a reaction, calculated as (actual yield / theoretical yield) x 100%.

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, reflecting the law of conservation of mass.

Front

How do you calculate moles from grams?

Back

To calculate moles from grams, use the formula: moles = mass (g) / molar mass (g/mol).

Front

What is a mole ratio?

Back

A mole ratio is a ratio between the amounts in moles of any two compounds involved in a chemical reaction.

Front

What is the significance of the coefficients in a balanced equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction and are used to determine mole ratios.

Front

How do you find the limiting reactant?

Back

To find the limiting reactant, calculate the moles of each reactant and determine which one produces the least amount of product.
