Question

determine the resulting ionic formula and names for the following pairs of cations/anions:
a.) Chromium (III)/ Sulfate
b.) Calcium/Nitrogen

Answer 1

\[\_Cr^{3+} + \_\left( SO_4 \right)^{2-}\]

balance the charges..

Answer 2

\[2Cr^{3+} + 3\left( SO_4 \right)^{2-} \to Cr_2\left( SO_4 \right)_3\]

Answer 3

\[3Ca^{2+}+2N^{3-} \to Ca_3N_2\]
