Explanation:

Step1: Identify compound type for $NaClO_3$

$NaClO_3$ is an ionic compound. Sodium ($Na^+$) is a metal and chlorate ($ClO_3^-$) is a poly - atomic ion. The name is sodium chlorate.

Step2: Identify compound type for $NH_3$

$NH_3$ is a molecular compound. It is named ammonia.

Step3: Identify compound type for $FeI_3$

$FeI_3$ is an ionic compound. Iron ($Fe$) is a transition metal with a + 3 charge here (since iodine has a - 1 charge and there are 3 iodines) and iodine ($I^-$). The name is iron(III) iodide.

Step4: Write formula for dicarbon dihydride

The prefix "di -" means 2. For carbon and hydrogen, the formula is $C_2H_2$.

Step5: Write formula for aluminum sulfate

Aluminum has a + 3 charge ($Al^{3 + }$) and sulfate has a - 2 charge ($SO_4^{2-}$). Using the criss - cross method, the formula is $Al_2(SO_4)_3$.

Step6: Write formula for phosphoric acid

Phosphoric acid contains hydrogen ($H^+$), phosphorus, and oxygen. The formula is $H_3PO_4$.

Chemical Formula	Chemical Name
$NH_3$	Ammonia
$FeI_3$	Iron(III) iodide

Chemical Name	Chemical Formula
Aluminum sulfate	$Al_2(SO_4)_3$
Phosphoric acid	$H_3PO_4$
