Sample Questions

1multiple correct

Which conditions are necessary for chemical reactions to occur?

Show answer

Mixing the substances in close contact, Supplying heat, Supplying light, Passing electricity

A chemical change can occur when reactant particles collide, and collisions happen when substances are brought into close contact or when energy is supplied. The chapter lists mixing, heat, light, electricity, pressure, and catalysts as conditions that can bring about reactions. Keeping reactants separated does not help collisions occur, so it is not a necessary condition.

2true false

Photosynthesis is an example of an endothermic reaction.

Show answer

True

Photosynthesis is an endothermic reaction because it requires energy input from sunlight to convert carbon dioxide and water into glucose and oxygen. Energy is absorbed during this process.
