Question

write the chemical formula of each of the acids listed in the table below. acid chemical formula iodic acid phosphoric acid nitrous acid hydrosulfuric acid

Explanation:

Step1: Recall iodic - acid formula

Iodic acid contains iodine, oxygen and hydrogen. Its formula is $HIO_{3}$.

Step2: Recall phosphoric - acid formula

Phosphoric acid has phosphorus, oxygen and hydrogen. Its formula is $H_{3}PO_{4}$.

Step3: Recall nitrous - acid formula

Nitrous acid consists of nitrogen, oxygen and hydrogen. Its formula is $HNO_{2}$.

Step4: Recall hydrosulfuric - acid formula

Hydrosulfuric acid has sulfur and hydrogen. Its formula is $H_{2}S$.

Answer:

acid	chemical formula
phosphoric acid	$H_{3}PO_{4}$
nitrous acid	$HNO_{2}$
hydrosulfuric acid	$H_{2}S$
