Front

What is the maximum amount of product that could be obtained from a chemical reaction?

Back

Theoretical yield

Front

What is the measured amount of a product obtained from a chemical reaction?

Back

Actual yield

Front

Which equation is balanced: PbO2 + 2H2, SO2 + H2O -> H2SO4, or 2Na + 2H2O -> 2NaOH + H2?

Back

2Na + 2H2O -> 2NaOH + H2

Front

What law governs the balancing of chemical equations?

Back

Law of Conservation of Matter/Mass

Front

How many molecules of water are produced from the combustion of 110 g of CH4 in the reaction CH4 + 2 O2 → CO2 + 2 H2O?

Back

8.3×10^25 molecules

Front

Define 'Theoretical Yield'.

Back

The maximum amount of product that can be produced from a given amount of reactants in a chemical reaction.

Front

Define 'Actual Yield'.

Back

The amount of product that is actually obtained from a chemical reaction.

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides of the equation.

Front

What is the significance of the Law of Conservation of Matter/Mass in chemistry?

Back

It states that matter cannot be created or destroyed in a chemical reaction, thus the mass of reactants equals the mass of products.

Front

What is a mole ratio?

Back

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