1- Calcium Hydroxide + Calcium Bicarbonate 2- Calcium Bicarbonate + Sodium Carbonate

3- Calcium Sulphate + Sodium Carbonate

4- Sodium compound + Calcium Sulphate

5- Carbon dioxide + Calcium Carbonate

6- Calcium Bicarbonate + Calcium Carbonate

Remember these followings :-

Acid + Base = salt + water

Acid + metal = salt + hydrogen

Acid + carbonates = salt + water + carbon dioxide

Base + ammonium salt = salt + ammonia + water

Base + acidic oxide = salt + water

I hope that you will be clear via these formulas.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
