Hope it helps you, please mark me as brainliest.

Explanation:

a) 3Fe + 4H2O → Fe3O4 + 4H2

Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation.

The chemical reaction is given as

Fe + H2O → Fe3O4+ H2

The balanced chemical equation can be written as

b) 2Pb(NO3)2 → 2PBO + 4NO2 + O2

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

• It is a decomposition reaction where a single type of chemical compound breaks down into two or more elements or new compounds.
• The produced lead monoxide PbO is yellow coloured and nitrogen oxide is liberated in the form of reddish fumes.

c) 2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)

Steps:

There are 3 Cl atoms on the product side and 1 on the reactant side. Add a coefficient of 3 in front of HCl. Al(s)+3HCl(aq)→AlCl3(aq)+H2(g)

There are 3 H atoms on the reactant side and 2 on the product side. The coefficient in front of HCl from 3 to 6, and add a coefficient of 3 in front of the H2. Al(s)+6HCl(aq)→AlCl3(aq)+3H2(g)

Here are now 6 Cl on the reactant side and 3 on the product side. Add a coefficient of 2 in front of AlCl3.

Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)

There is 1 Al on the reactant side and 2 Al on the product side. Add a coefficient in front of Al on the reactant side.
