Question

Розставте коефіцієнти у рівняннях реакцій: ● Mg + H2SO4 → MgSO4 + S + H2O● Fe2O3 + H2O → Fe(OH)3● Al + H2SO4 → Al2(SO4)3 + H2​

Answer 1

Ответ:

3Mg + 4H2SO4 => 3MgSO4 + S + 4H2O

Fe2O3 + 3H2O => 2Fe(OH)3

2Al + 3H2SO4 => Al2(SO4)3 + 3H2

Answer 2

I can help you with your chemistry homework. Here are the balanced equations for the reactions you asked:

● $3Mg + 4H_2SO_4 \rightarrow 3MgSO_4 + S + 4H_2O$

● $Fe_2O_3 + 3H_2O \rightarrow 2Fe(OH)_3$

● $2Al + 3H_2SO_4 \rightarrow Al_2(SO_4)_3 + 3H_2$

To balance the equations, you need to find the coefficients that make the number of atoms of each element equal on both sides of the arrow. You can use the method of electron balance or the method of inspection. For more details, you can check these sources: , , .
