Question

A)P → P205 → H3PO4 → K3PO4помогите ​

Answer 1

Ответ:

(ХИМИЧЕСКОЕ УРАВНЕНИЕ)

P->P2O5->H3PO4->K3PO4

4 P+5 O2 = 2 P2O5

P2O5+3 H2O = 2 H3PO4

H3PO4+3 KOH = K3PO4 + 3 H2O

Balancing Chemical Equations

To balance the chemical equation P + O2 → P2O5 → H3PO4 → K3PO4, we need to ensure that the same number of each type of atom is present on both sides of the equation.

Balancing the Equation Step by Step

1. Balancing P and O in P + O2 → P2O5: - There are 2 phosphorus (P) atoms on the right side, so we need to put a coefficient of 2 in front of P on the left side to balance the phosphorus atoms. - This gives us the balanced equation: P4 + 5O2 → P2O5.

2. Balancing O in P2O5 → H3PO4: - There are 4 oxygen (O) atoms on the left side and 7 on the right side. To balance the oxygen atoms, we need to put a coefficient of 4 in front of H3PO4 on the right side. - This gives us the balanced equation: P4 + 5O2 → P2O5 → 2H3PO4.

3. Balancing H and P in H3PO4 → K3PO4: - There are 3 hydrogen (H) atoms on the left side and 6 on the right side. To balance the hydrogen atoms, we need to put a coefficient of 2 in front of H3PO4 on the left side. - There are 1 phosphorus (P) atom on the left side and 1 on the right side, so the phosphorus atoms are already balanced. - This gives us the balanced equation: 2H3PO4 → K3PO4.

Final Balanced Equation

The final balanced chemical equation is: P4 + 5O2 → 2H3PO4 → K3PO4.
