Question

calcium phosphate express your answer as a chemical formula. a chemical reaction does not occur for this question.

Explanation:

Step1: Identify ions

Calcium ion: $Ca^{2+}$, Phosphate ion: $PO_4^{3-}$.

Step2: Balance charges

To balance charges, find the least common multiple of 2 and 3, which is 6. So, number of $Ca^{2+}$: $\frac{6}{2}=3$, number of $PO_4^{3-}$: $\frac{6}{3}=2$.

Step3: Write formula

Combine ions: $Ca_3(PO_4)_2$.

Answer:

$Ca_3(PO_4)_2$
