Question

Fe +H2O ->Fe3O4 + H2 найти сумму коэффициентов уравнения реакций.

Answer 1

3Fe + 4H2O -> Fe3O4 + 4H2
Сумма коэффициентов равна 12

Answer 2

3Fe+4H2O-->Fe3O4+4H2
3+4+1+4 = 12
ответ 12

Answer 3

Balancing the Chemical Equation

To balance the chemical equation Fe + H2O -> Fe3O4 + H2 and find the sum of the coefficients, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The balanced chemical equation for the given reaction is: Fe + 4H2O -> Fe3O4 + 4H2

Sum of Coefficients

The sum of the coefficients in the balanced chemical equation is 1 + 4 + 1 + 4, which equals 10.

This balanced equation ensures that the law of conservation of mass is obeyed, as the same number of each type of atom is present on both sides of the equation.
