Type of Chemical Reactions

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light. Example: Water freezing in a freezer.

Front

What type of reaction occurs when hydrogen and oxygen combine to form water?

Back

Synthesis reaction.

Front

What is fission in nuclear reactions?

Back

Fission is the splitting of a heavy nucleus into two lighter nuclei, releasing energy.

Front

What is fusion in nuclear reactions?

Back

Fusion is the combination of two light nuclei to form a heavier nucleus, releasing energy.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay where a neutron in a nucleus transforms into a proton and emits an electron.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay where a nucleus emits an alpha particle, which consists of two protons and two neutrons.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a 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 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 chemical reaction where the ions of two compounds exchange places in an aqueous solution to form two new compounds.

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.
