What is a chemical change?

Back

A chemical change is a process where one or more substances are transformed into different substances with distinct properties, often involving a chemical reaction.

Front

Give an example of a chemical change.

Back

Using magnesium to displace hydrogen gas from water is an example of a chemical change.

Front

What type of reaction is represented by the equation Al(OH)3 → Al2O3 + H2O?

Back

This is a decomposition reaction.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one reactant breaks down into two or more products.

Front

What type of reaction is represented by the equation NH3 + HCl → NH4Cl?

Back

This is a synthesis reaction.

Front

What is 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

What is the generalized equation for a synthesis reaction?

Back

The generalized equation for a synthesis reaction is A + B → AB.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction combines reactants to form a single product, while a decomposition reaction breaks down a single reactant into multiple products.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is the formation of water from hydrogen and oxygen: 2H2 + O2 → 2H2O.

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.
