Chemical Reactions and Equations

Flashcards on chemical reactions and equations, covering types of reactions, oxidation, reduction, and everyday effects.

A reaction in which a single product is formed from two or more reactants is known as a __ reaction.

combination

Reactions in which heat is released along with the formation of products are called __ chemical reactions.

exothermic

The decomposition of vegetable matter into __ is an example of an exothermic reaction.

compost

When a decomposition reaction is carried out by __, it is called thermal decomposition.

heating

Reactions in which energy is __ are known as endothermic reactions.

absorbed

In a displacement reaction, one element __ another element from its compound.

displaces

Any reaction that produces a __ can be called a precipitation reaction.

precipitate

Reactions in which there is an exchange of ions between the reactants are called __ reactions.

double displacement

If a substance __ oxygen during a reaction, it is said to be oxidized.

gains

If a substance __ oxygen during a reaction, it is said to be reduced.

loses

Reactions in which one reactant gets oxidized while the other gets reduced are called __ reactions or redox reactions.

oxidation-reduction

When a metal is attacked by substances around it, such as moisture or acids, it is said to __ and this process is called corrosion.

corrode
