Question

+koh+h20=h3p+kh2po2 овр

Answer 1

P⁰+KOH+H₂O → P⁻³H₃+KH₂P⁺O₃

P⁰ + 3e⁻→ P⁻³   3         1

                             3          

P⁰ - e⁻→ P⁺      1          3

P⁰ окислитель              (P⁰ + 3e⁻→ P⁻³)

P⁰ восстановитель      (P⁰ - e⁻→ P⁺)

4P+2KOH+4H₂O = 2PH₃+2KH₂PO₃

Answer 2

The chemical equation you've provided seems to involve reactions between potassium hydroxide (KOH), water (H2O), phosphine (PH3), and potassium dihydrogen phosphate (KH2PO2). However, the equation appears to be unbalanced. To balance it, we need to ensure that the same number of atoms of each element are present on both sides of the equation.

The balanced chemical equation for the reaction you mentioned is:

2 KOH + 3 H2O → PH3 + KH2PO2
