Front

Define a base in terms of proton acceptance.

Back

A base is a substance that accepts protons (H⁺ ions).

Front

What is the significance of the theoretical yield in a chemical reaction?

Back

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

Front

Explain the concept of oxidation number.

Back

The oxidation number is a measure of the degree of oxidation of an atom in a compound.

Front

What is the role of water in combustion reactions?

Back

Water is one of the products formed when hydrocarbons combust.

Front

How do you calculate the actual yield of a reaction?

Back

The actual yield is determined by measuring the amount of product obtained from the reaction.
