Types of Reactions

Question 1

Synthesis

Answer 1

1. Combination of elements
2. Metallix oxide + water = base
3. Nonm oxide + water = acid
4. Metallic oxide + Nonm oxide= salt ( ionic)

Question 2

Decomposition

Answer 2

1. Bases heated = water + metallic oxide
2. Acids heated = water + Nonm oxide
3. Metallic carbonate heated= metallic oxide + carbon dioxide gas ( arrow)
