Balancing and Types of Chemical Equations

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light.

Front

What type of reaction occurs when two or more substances combine to form a single product?

Back

Synthesis reaction.

Front

What does the Law of Conservation of Mass state?

Back

Matter cannot be gained or lost in a chemical reaction.

Front

How many elements are present in the compound C6H12O6?

Back

3 elements: Carbon (C), Hydrogen (H), and Oxygen (O).

Front

What is a coefficient in a chemical equation?

Back

The large number in front of a chemical formula that indicates the number of molecules or moles of that substance.

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

What is the difference between a reactant and a product in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change, while products are the substances formed as a result of the reaction.

Front

What is a balanced chemical equation?

Back

A chemical equation in which the number of atoms for each element is the same on both sides of the equation.

Front

What is the purpose of balancing a chemical equation?

Back

To ensure that the Law of Conservation of Mass is obeyed, meaning the same number of each type of atom is present before and after the reaction.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings.
