Question

H2SO4 (КОНЦЕТРАТ)+Mg->MgSO4+H2S+H2O добавьте коэффициенты методом электронного баланса

Answer 1

5H2SO4 + 4Mg = 4MgSO4 + H2S + 4H2O
Mg - 2e = Mg⁺² x4 в-ль
S⁺⁶ + 8e = S⁻² x1 о-ль

Answer 2

Balancing the Chemical Equation: H2SO4 + Mg -> MgSO4 + H2S + H2O

To balance the chemical equation H2SO4 + Mg -> MgSO4 + H2S + H2O using the method of electron balance, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The unbalanced equation is: H2SO4 + Mg -> MgSO4 + H2S + H2O

Balancing Steps:

1. Start by balancing the elements that appear only once on each side of the equation. 2. Balance the hydrogen atoms first, then the sulfur atoms, and finally the oxygen atoms.

Balancing the Equation:

The balanced chemical equation is: H2SO4 + Mg -> MgSO4 + H2S + H2O To balance the equation, the coefficients are: H2SO4 + Mg -> MgSO4 + H2S + H2O 1 + 1 -> 1 + 1 + 1

Therefore, the balanced equation is: H2SO4 + Mg -> MgSO4 + H2S + H2O
