What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

What is the general formula for a double replacement reaction?

Back

AB + CD -> CB + AD, where two compounds exchange ions.

Front

Back

Decomposition, as a single compound breaks down into two or more products.

What is combustion in terms of chemical reactions?

Back

Combustion is a reaction where a substance combines with oxygen to produce heat and light, typically forming carbon dioxide and water.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two or more atomic nuclei combine to form a larger nucleus, releasing energy.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a large nucleus into smaller nuclei, while fusion is the combining of small nuclei to form a larger nucleus.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another in a compound, represented as A + BC -> AC + B.

Front

What is a combination reaction?

Back

A combination reaction is a chemical reaction where two or more substances combine to form a single product, represented as A + B -> AB.

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; the total mass of reactants equals the total mass of products.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
