_{2}+\boldsymbol{6} \boldsymbol{S} \boldsymbol{i} \boldsymbol{O}_{2}+\mathbf{1 0
\( \mathbf{2} \boldsymbol{C} \boldsymbol{a}_{3}\left(\boldsymbol{P} \boldsymbol{O}_{4}\right)_{2}+\boldsymbol{6} \boldsymbol{S} \boldsymbol{i} \boldsymbol{O}_{2}+\mathbf{1 0} \boldsymbol{C} \rightarrow \boldsymbol{P}_{4}+ \) \( \boldsymbol{C a} \boldsymbol{S i O}_{3}+\mathbf{1 0 C O} \) Which coefficient balances the reaction given above?
- A. 2
- B. 4
- C. 5
- D. 6
Step-by-step solution
Balancing the reaction: left side has 6 Ca, 4 P, 6 Si, 28 O, 10 C. Right side: P4 gives 4 P, 10 CO gives 10 C and 10 O, and x CaSiO3 gives x Ca, x Si, 3x O. Balancing Ca: x=6; checking O: 10+3*6=28, matches left. Thus coefficient is 6.
