What net ionic equation describes the reaction when these solutions are mixed? na3po4 (aq) + cacl2(aq) → na+(aq) + cl– (aq) → nacl(s) 2ca2+(aq) + na+(aq) → naca2(s) 2po43–(aq) + 3ca2+(aq) → ca3(po4)2(s) 2po43–(aq) + cl– (aq) → cl2(po4)3(s)

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the answer is c
