What is the final chemical equation from these intermediate chemical equations? cap p sub 4 cap o sub 6 s rightarrow cap p sub 4 times s plus 3 cap o sub 2 g cap p sub 4 times s plus 5 cap o sub 2 g rightarrow cap p sub 4 cap o sub 10 s

Add the two equations: P₄O₆(s) → P₄(s) + 3O₂(g) and P₄(s) + 5O₂(g) → P₄O₁₀(s). The P₄(s) appears on both sides, so it cancels; 3O₂ is produced and 5O₂ is consumed, leaving 2O₂ consumed overall. The final equation is P₄O₆(s) + 2O₂(g) → P₄O₁₀(s), choice B.
