D)2,10,8

Question

Quizplus · Accepted Answer

To balance the equation, start with phosphorus (P). There is 1 P4 on the left, meaning 4 P atoms, which matches with 4 PH3 molecules on the right (each containing 1 P), so the phosphorus atoms are balanced with 1 P4 and 4 PH3. Next, balance hydrogen (H). There are 4 PH3 molecules on the right, each with 3 H atoms, totaling 12 H atoms. To balance hydrogen, you need 6 H2 molecules on the left (since each H2 has 2 H atoms, and 6*2=12). Therefore, the balanced equation is P4 + 6H2 → 4PH3.
