An aqueous solution of $${\mathrm{CaBr}}_2$$ is mixed with an aqueous solution of $${\mathrm{Na}}_3{\mathrm{PO}}_4$$ and a white precipitate forms. 1st attempt Part 1 (1 point) Which of the following is the correct formula for the precipitate? Choose one: $$\begin{array}{l}{\mathrm{Ca}}_2{\left({\mathrm{PO}}_4\right)}_3\\ {\mathrm{Ca}}_3{\left({\mathrm{PO}}_4\right)}_2\\ {\mathrm{CaPO}}_4\\ {\mathrm{Na}}_2\mathrm{Ca}\\ \mathrm{NaBr}\end{array}$$ Which of the following ions will appear in the net ionic equation for this reaction? Choose one or more: $${\mathrm{PO}}_4^{3?}$$ $${\mathrm{Ca}}^{3+}$$ $${\mathrm{Ca}}^{2+}$$ $${\mathrm{Br}}^{?}$$ $${\mathrm{Na}}^{+}$$
