Front

What are products in a chemical equation?

Back

Substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

How do you determine the number of atoms in a chemical equation?

Back

By using the coefficients and subscripts in the chemical formula.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is a coefficient in a chemical equation?

Back

A number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved.

Back

An element is a pure substance made of one type of atom, while a compound is made of two or more different types of atoms chemically bonded together.

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides, reflecting the law of conservation of mass.

Front

What is a synthesis reaction?

Back

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