What coefficients balance the following equation? ____ P4 (s)+ ____ H₂ (g)→ ____ PH₃ (g)

Question

Quizplus · Accepted Answer

To balance the equation P4 + 6H2 → 4PH3, each element must have the same number of atoms on both sides. P4 has 4 P atoms, so we need 4 PH3 molecules to have 4 P atoms on the product side. To balance H, 4 PH3 molecules have 3*4=12 H atoms, requiring 6 H2 molecules (since each H2 molecule has 2 H atoms, 6*2=12) to balance the hydrogen atoms.
