Question

Study the following unbalanced redox reaction. Which one of the following choices represents the balanced redox equation? P4 + O2→ P4O10

P4→ P4 + 2e−

P4 + O2→ P4

P4 + 4O2→ 4P4O10

P4 + 5O2→ P4O10

Answer 1

The correct answer would be P₄ + 5O₂ → P₄O₁₀

Also D for Plato

Answer 2

In order to balance chemical reaction equation, we apply the principle of conservation of mass, which states that the total mass in a system remains constant. Therefore, the amount of each substance on the left side of the equation is the same as that on the right. The equation is:
P₄ + O₂ → P₄O₁₀

Balancing:
P₄ + 5O₂ → P₄O₁₀
