Answer 1

В скобках степень окисления))))
2P(0)+5Cu(+2)S(+6)O4(-2)+8H2(+1)O(-2)=2H3(+1)P(+5)O4(-2)+5Cu(0)+5H2(+1)S(+6)O4(-2)

Answer 2

Balancing Chemical Equation:

The given chemical equation is unbalanced. To balance it, 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: 2P + 5CuSO4 + 8H2O = 2H3PO4 + 5Cu + 5H2SO4

Balancing the Equation:

To balance the equation, we can follow these steps: 1. Start by balancing the elements that appear only once on each side of the equation. 2. Balance the elements that appear more than once on either side of the equation. 3. Finally, verify that the equation is balanced by counting the atoms of each element on both sides.

Balancing the Equation Step by Step:

1. Balancing Phosphorus (P): - There are 2 phosphorus atoms on the left side and 2 on the right side, so phosphorus is already balanced.

2. Balancing Copper (Cu): - There are 5 copper atoms on the left side and 5 on the right side, so copper is already balanced.

3. Balancing Sulfur (S): - There are 4 sulfur atoms on the left side (5 from CuSO4 and 8 from H2SO4) and 4 on the right side (5 from H2SO4), so sulfur is already balanced.

4. Balancing Oxygen (O): - There are 8 oxygen atoms from H2O on the left side and 26 oxygen atoms on the right side (16 from H3PO4 and 10 from H2SO4). To balance oxygen, we can add 9 molecules of O2 to the left side.

5. Balancing Hydrogen (H): - There are 16 hydrogen atoms from H2O on the left side and 14 hydrogen atoms on the right side (6 from H3PO4 and 8 from H2SO4). To balance hydrogen, we can add 2 molecules of H2O to the right side.

The balanced chemical equation is: 2P + 5CuSO4 + 17H2O = 2H3PO4 + 5Cu + 10H2SO4

Conclusion:

The balanced chemical equation for the given reaction is 2P + 5CuSO4 + 17H2O = 2H3PO4 + 5Cu + 10H2SO4.
