in the balanced equation -aFe2O3+bH2=cFe+dH2O, find the value of a, b, c, d are respectively A) 1,1,2,3 B) 1,1,1,1 C) 1,3,2,3 D) 1,2,2,3

Answer 1

The value of a, b, c and d for the given chemical equation are 1, 3, 2 and 3

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Every balanced chemical equation follows law of conservation of mass.

For the given chemical reaction, the balanced equation follows:

$Fe_2O_3+3H_2\rightarrow 2Fe+3H_2O$

By Stoichiometry of the reaction:

1 mole of iron (III) oxide reacts with 3 moles of hydrogen gas to produce 2 moles of iron and 3 moles of water molecule.
