Balancing Chemical Equations and types of Reactions

Front

What is an exothermic reaction?

Back

A reaction that releases heat to its surroundings.

Front

What is an endothermic reaction?

Back

A reaction that absorbs heat from its surroundings.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.

Front

What are coefficients in a chemical equation?

Back

Numbers placed before compounds to indicate the number of molecules involved in the reaction.

Front

What are subscripts in a chemical formula?

Back

Numbers that indicate the number of atoms of an element in a molecule.

Front

How do you balance a chemical equation?

Back

By adjusting the coefficients to ensure the same number of each type of atom on both sides of the equation.

Front

What happens to the rate of a chemical reaction when temperature increases?

Back

The reaction rate usually increases.

Front

What is a synthesis reaction?

Back

A type of reaction where two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

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

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound.
