Question

СРОЧНО ПОЖАЛУЙСТА! Закончите уравнения реакций, расставьте коэффициенты: Pb + H2SO4 → FeSO4  +  KOH  → Na2S + H2SO4 →​

Answer 1

Объяснение:

Pb + H2SO4 → PbSO4 + H2↑

FeSO4  + 2 KOH  → K2SO4 + Fe(OH)2↓

Na2S + H2SO4 → Na2SO4 + H2S↑

Answer 2

Balancing Chemical Equations

To balance the given chemical equations, we'll start by writing out the unbalanced equations and then proceed to balance them.

1. Pb + H2SO4 → FeSO4 + KOH → Na2S + H2SO4 →

Let's balance each equation step by step.

Pb + H2SO4 → PbSO4 + H2

This equation is already balanced.

FeSO4 + KOH → Fe(OH)2 + K2SO4

This equation is already balanced.

Na2S + H2SO4 → Na2SO3 + H2S

This equation is already balanced.

Therefore, the balanced equations are:

Pb + H2SO4 → PbSO4 + H2

FeSO4 + KOH → Fe(OH)2 + K2SO4

Na2S + H2SO4 → Na2SO3 + H2S

Each equation is balanced with the appropriate coefficients.

I hope this helps! If you have any other questions, feel free to ask.
