Question

Balance H2SO4+HI --- H2S + I2+ H2O

Answer 1

H2SO4 + 8HI---H2S + 4I2+4H2O

Answer 2

Answer:

H2SO4 + 8HI → H2S + 4I2 + 4H2O

Explanation:

Balancing chemical equations includes the addition of the stoichiometric coefficients to the reactants and products. This is very important because a chemical equation obey the law of conservation of mass and the law of constant proportions which means the same number of atoms of each element exists on the reactant side and the product side of the equation.

Chemical equation

A chemical equation is a representation of a chemical reaction in which the reactants and products are denoted by their respective chemical formulae.

Stoichiometric Coefficient

A stoichiometric coefficient is the total number of molecules of a chemical species that participate in a chemical reaction.
