castortr0y [4]

Answer:

-162,5 kJ/mol

Explanation:

Cl(g) + 2O2(g) --> ClO(g) + O3(g)  ΔH = 122.8 kJ/mol (as we used the reaction in the opposite direction, it will turn the enthalpy from exothermic to endothermic)

2O3(g) --> 3O2(g)   ΔH = -285.3 kJ/mol

  Cl(g) + O2(g) --> ClO(g) + O3(g)  ΔH = 122.8 kJ

+ 2O3 (g)          --> 3O2(g)              ΔH = - 285.3 kJ

O3(g) + Cl(g)     --> ClO(g) + 2O2(g)  ΔH = 122.8 + (-285.3) = -162,5 kJ

kenny6666 [7]

Answer:

1)   P₄ + 5O₂ → P₄O₁₀  redox reaction

2)   P₄O₁₀ + 6H₂O → 4H₃PO₄  acid-base reaction

3)   Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄  precipitation reaction

Explanation:

The reactions that take place in the <u>electric furnace method</u> are:

1)   P₄ + 5O₂ → P₄O₁₀

This is a redox reaction, because the oxidation state of the reactants is changed.

2)   P₄O₁₀ + 6H₂O → 4H₃PO₄

This is an acid-base reaction, because there's an exchange of H⁺ species.

The reaction that takes place in the <u>wet process</u> is:

3)   Ca₅(PO₄)₃F + 5H₂SO₄ → 3H₃PO₄ + HF + 5CaSO₄

This is an precipitation reaction, because a precipitate (a solid phase in a liquid phase) is formed.
