Stoichiometry

Front

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.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

How do you calculate moles from grams?

Back

Moles = Mass (g) / Molar Mass (g/mol).

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 conservation of mass.

Front

What is the mole ratio in a chemical reaction?

Back

The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

Front

How do you determine the limiting reactant?

Back

The limiting reactant is the substance that is completely consumed first in a chemical reaction, limiting the amount of product formed.

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, calculated using stoichiometry.

Front

What is the actual yield?

Back

The actual yield is the amount of product that is actually obtained from a chemical reaction, which is often less than the theoretical yield.

Front

How do you calculate percent yield?

Back

Percent Yield = (Actual Yield / Theoretical Yield) x 100%.

Front

What is STP in chemistry?

Back

STP stands for Standard Temperature and Pressure, which is defined as 0 degrees Celsius (273.15 K) and 1 atmosphere pressure.
