li3(po4)2
li(po4)3
li3(po3)
lipo4
question 2

choose the correct name for hno3.
nitrous acid
ammoniumic acid
hydronitric acid
nitric acid

Explanation:

Step1: Determine lithium ion charge

Lithium is in group 1 of the periodic - table, so it forms a $Li^+$ ion with a +1 charge.

Step2: Determine phosphate ion charge

The phosphate ion is $PO_4^{3 -}$, with a - 3 charge.

Step3: Balance charges

To balance the charges in an ionic compound, we need 3 lithium ions for every 1 phosphate ion. So the formula is $Li_3PO_4$.

Step4: Identify $HNO_3$ name

$HNO_3$ is a strong acid. The name of $HNO_3$ is nitric acid. Nitrous acid is $HNO_2$. There is no such thing as ammoniumic acid. Hydronitric acid is $HN_3$.

Answer:

First question: $Li_3PO_4$
Second question: nitric acid
