Question

Расставить коэффициенты и рассчитать методом электронного баланса Zn+H2SO4->ZnSO4+H2

Answer 1

окислительно-восстановительная реакция

Zn(0)+H2(+1)SO4=Zn(+2)SO4+H2(0)     (в скобочках поставлены степени окисления они пишутся вверху)

  Zn(0)-2е=Zn(+2)           окисление

  2H(+)+2e=H2(0)           восстановление

Zn(0) - восстановитель

H2(+)SO4 - окислитель

если вы решали подобные задачи, то думаю мое решения вам будет ясно))

Answer 2

Balancing the Chemical Equation Zn + H2SO4 -> ZnSO4 + H2

To balance the chemical equation Zn + H2SO4 -> ZnSO4 + H2, we'll follow these steps:

1. Write the Unbalanced Equation: The unbalanced equation is: Zn + H2SO4 -> ZnSO4 + H2

2. Balance the Atoms: Start by balancing the atoms in the equation. In this case, we have: - Zinc (Zn) - Hydrogen (H) - Sulfur (S) - Oxygen (O)

3. Balance the Equation: - First, balance the elements that appear only once on each side of the equation. - Then, balance the remaining elements.

4. Calculate Using the Electron Balance Method: The electron balance method involves balancing the redox reaction by comparing the increase and decrease in the oxidation states of the elements involved.

Using the electron balance method, we can determine the coefficients for the balanced equation.

Let's proceed with the calculation using the electron balance method.

Calculation Using the Electron Balance Method

The electron balance method involves comparing the increase and decrease in the oxidation states of the elements involved in the reaction.

The oxidation states of the elements in the given reaction are as follows: - Zinc (Zn) has an oxidation state of 0. - Hydrogen (H) has an oxidation state of +1. - Sulfur (S) has an oxidation state of +6 in H2SO4 and +4 in ZnSO4.

Now, let's calculate the coefficients using the electron balance method.

Balanced Equation Using the Electron Balance Method

The balanced equation for the given reaction Zn + H2SO4 -> ZnSO4 + H2 is: Zn + H2SO4 -> ZnSO4 + H2
