Answer 2

Answer:

The compound used for testing co2 gas is -Calcium hydroxide solution

The main four types of reactions are h

Combination reaction-Two or more compounds combine to form one compound. A + B → AB

Decomposition reaction -The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. AB → A + B

Precipitation reaction -Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. A + Soluble salt B → Precipitate + soluble salt C

Neutralization reaction- An acid and a base react with each other. Generally, the product of this reaction is a salt and water. Acid + Base → Salt + Water
