This reaction cannot produce calcium chromate.

#### Explanation:

This reaction cannot occur. In order for one of the products to be calcium chromate, one of the reactants would have to contain the chromate ion, $\text{CrO"^(2-)}$.

The actual chemical reaction between calcium nitrate and sodium carbonate produces sodium nitrate and calcium carbonate.

$\text{Ca(NO"_3)_2" + Na"_2"CO"_3}$$\rightarrow$$\text{2NaNO"_3" + CaCO"_3}$
