Balance the following equation. KMnO 4 + HCl → KCl + H 2 O + MnCl 2 + Cl 2

A balanced equation is an equation for a chemical reaction in which the total number of the reactants and the products should be same. 2 KMnO 4 + 16 HCl → 2 KCl + 2 MnCl 2 + 8 H 2 O + 5 Cl 2 . The 2 moles of potassium permanganate reacts with the 16 moles of HCl gives 2 moles of KCl .

Balance the following equation. N 2 + H 2 → NH 3

A balanced equation is an equation for a chemical reaction in which the total number of the reactants and the products should be same. N 2 + 3 H 2 → 2 NH 3 . The one moles of nitrogen reacts with three moles of hydrogen to gives two moles of ammonia.

Balance the following equation. Fe + O 2 → Fe 2 O 3

A balanced equation is an equation for a chemical reaction in which the total number of the reactants and the products should be same. 4 Fe + 3 O 2 → 2 Fe 2 O 3 Four moles of iron reacts with three moles of oxygen to gives two moles of iron oxide.

Balance the following equation. Mg + O 2 → MgO

A balanced equation is an equation for a chemical reaction in which the total number of the reactants and the products should be same. 2 Mg + O 2 → 2 MgO Two moles of magnesium reacts with one mole of oxygen to give two moles of magnesium oxide.

Balance the chemical equation CaCO 3 → Heat CaO + CO

A balanced equation is an equation for a chemical reaction in which the total number of the reactants and the products should be same. The thermal decomposition of one mole of calcium carbonate to produce one mole of solid calcium oxide and one mole of carbon dioxide gas. This reaction takes place at a temperature of 900 - 1200 ° C . CaCO 3 → Heat CaO + CO 2
