Unit 8: Reactions & Equations Check for Understanding

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 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 are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

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 displacement reaction?

Back

A single displacement reaction is a chemical reaction where one element replaces another element in a compound.

Front

Why is it important to balance chemical equations?

Back

It is important to balance chemical equations to ensure that the same number of each type of atom is present on both sides, in accordance with the law of conservation of mass.

Front

What does it mean to balance an equation?

Back

Balancing an equation means adjusting the coefficients of the reactants and products so that the number of atoms of each element is equal on both sides.
