Certainly! Let's go through each word equation step-by-step.

### (i) Acid + Base → ______ and ______

1. When an acid reacts with a base, it results in the formation of a compound and water.
2. This type of reaction is known as a neutralization reaction.
3. The compound formed when an acid reacts with a base is called a salt.
4. Therefore, the products of this reaction are salt and water.

So the completed equation is:
Acid + Base → Salt and Water

### (ii) Acid + Metal → ______ and ______

1. When an acid reacts with a metal, it results in the formation of a compound and a gas.
2. The compound formed in this reaction is also a salt.
3. The gas released in this type of reaction is hydrogen gas.
4. Therefore, the products of this reaction are salt and hydrogen gas.

So the completed equation is:
Acid + Metal → Salt and Hydrogen gas

In summary:
(i) Acid + Base → Salt and Water
(ii) Acid + Metal → Salt and Hydrogen gas
