**Types of Chemical Reactions

Front

What are the four main types of chemical reactions?

Back

Synthesis, Decomposition, Single Replacement, Double Replacement.

Front

Define a synthesis reaction.

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

Define a decomposition reaction.

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds.

Front

What happens to atoms during a chemical reaction?

Back

Atoms are never lost or gained; they are just rearranged.

Front

In a chemical equation, what are the substances on the left side of the arrow called?

Back

Reactants.

Front

In a chemical equation, what are the substances on the right side of the arrow called?

Back

Products.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is an example of a synthesis reaction?

Back

2H₂ + O₂ → 2H₂O (Hydrogen gas combines with oxygen gas to form water).
