Calcium phosphate is produced when solutions of calcium chloride and sodium phosphate are mixed and react. $x\text{CaCl}_2 + y\text{Na}_3\text{PO}_4 \rightarrow 2\text{Ca}_3(\text{PO}_4)_2 + 12\text{NaCl$ What values of $x$ and $y$ balance the equation?
- A$x = 2,\ y = 2$
- B$x = 3,\ y = 4$
- C$x = 6,\ y = 3$
- D$x = 6,\ y = 4$
