Q.9: In an ordinary chemical reaction, -------- are neither created or destroyed.

Q.10: The total number of atoms before and after a chemical reaction takes place must be ---------.

Q.11: Balancing an equation for a reaction ensures that the number of each type of atom is -------- on both sides of the equation.

Q.12: A reaction where a solid is formed is called a --------- reaction.

Q.13: When an ionic compound dissolves in water, the resulting solution contains separated --------.
