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

The correct answer would be P₄ + 5O₂ → P₄O₁₀
