Define an exothermic reaction.

Back

A reaction that releases heat to its surroundings.

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is the amount of product obtained from a reaction, while theoretical yield is the maximum amount of product that could be formed from the given reactants.

What is the significance of the half-life in radioactive decay?

Back

It is the time required for half of the radioactive atoms in a sample to decay.

What does a negative ΔH indicate about a reaction?

Back

It indicates that the reaction is exothermic.
