WK 09 Flashcard: Identify Types of Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical process in which a substance combines with oxygen to produce heat and light, resulting in the formation of carbon dioxide and water.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is: Fuel + O2 → CO2 + H2O.

Front

What happens in all chemical changes?

Back

In all chemical changes, a new substance is formed.

Front

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.

Front

How do you balance the equation HgO → Hg + O?

Back

The balanced equation is 2HgO → 2Hg + O2.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

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 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.
