Front

How do you balance a chemical equation?

Back

By ensuring that the number of atoms for each element is the same on both sides of the equation.

Front

What is a limiting reactant?

Back

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

Front

What is the difference between a reactant and a product?

Back

Reactants are the starting materials in a chemical reaction, while products are the substances formed as a result of the reaction.

Front

What does it mean to say a reaction is in equilibrium?

Back

A reaction is in equilibrium when the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

Front

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

Back

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

Front

What is the molar mass of a compound?

Back

The molar mass of a compound is the mass of one mole of that compound, calculated by summing the atomic masses of all atoms in its formula.
