Question

balance the equation= Fe+H2SO4 Fe2(SO4)3+H2------>

Answer 1

2Fe+ H2SO4 ---> Fe(SO4)3+ 3H2

Answer 2

Answer:

An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and the total charge for each component of the reaction.

Explanation:

In the given chemical equation, the number of atoms on both sides of the reaction is:

On the reactant's side.

Fe = 1

H = 2

S = 1

O = 4

On product's side,

Fe = 2

H = 2

S = 3

O = 12

For balancing the given chemical reaction equation, we have to take 2 mol of Fe and 3 mol of sulphuric acid. This results in the formation of one mole  $Fe_{2} (SO_{4} )_{3}$ and 3 moles $H_{2}$.

Therefore, the complete balanced chemical reaction equation is:

                       $2Fe$ +  $3H_{2} SO_{4}$ → $Fe_{2} (SO_{4} )_{3}$ + $3H_{2}$

Thus, the number of atoms on both sides of the complete balanced chemical equation reaction is:

On the reactant's side.

Fe = 2

H = 6

S = 3

O = 12

On product's side,

Fe = 2

H = 6

S = 3

O = 12

Hence the complete balanced chemical reaction equation is $2Fe$ + $3H_{2} SO_{4}$ → $Fe_{2} (SO_{4} )_{3}$  + $3H_{2}$.
