question 3 of 10
which of the following best describes a balanced reaction?
a. a reaction that has the same number of molecules on each side of the equation
b. a reaction that has the same type of atoms on each side of the equation
c. a reaction that has the same number and type of atoms on each side of the equation
d. a reaction that has the same number of atoms on each side of the equation

Explanation:

In a balanced chemical - reaction, the law of conservation of mass is obeyed. This means that the number and type of atoms on the reactant side must be equal to the number and type of atoms on the product side. It's not just about the number of molecules (as different molecules can have different numbers of atoms) or just the type of atoms (the quantity also matters), and not just the number of atoms without considering the type.

Answer:

C. A reaction that has the same number and type of atoms on each side of the equation
