Question

1. write the formulas for the following:

a. lithium oxide
b. calcium nitride
c. ferrous bromide
d. ammonium nitrate
e. aluminum sulfate
f. sulfur dibromide
g. carbon dioxide
h. carbon tetrachloride
i. nitrous acid
j. sulfuric acid

Explanation:

Step1: Determine the formula for sulfur dibromide

Sulfur is \(S\) and bromide is \(Br\). The prefix "di -" means 2. So the formula is \(SBr_{2}\).

Step2: Determine the formula for carbon dioxide

Carbon is \(C\) and oxide is \(O\). The prefix "di -" means 2. So the formula is \(CO_{2}\).

Step3: Determine the formula for carbon tetrachloride

Carbon is \(C\) and chloride is \(Cl\). The prefix "tetra -" means 4. So the formula is \(CCl_{4}\).

Step4: Determine the formula for nitrous acid

Nitrous acid has the formula \(HNO_{2}\).

Step5: Determine the formula for sulfuric acid

Sulfuric acid has the formula \(H_{2}SO_{4}\).

Answer:

a. \(Li_{2}O\)
b. \(Ca_{3}N_{2}\)
c. \(FeBr_{2}\)
d. \(NH_{4}NO_{3}\)
e. \(Al_{2}(SO_{4})_{3}\)
f. \(SBr_{2}\)
g. \(CO_{2}\)
h. \(CCl_{4}\)
i. \(HNO_{2}\)
j. \(H_{2}SO_{4}\)
