Question

match the chemical name with the appropriate chemical formula
1 carbon tetrafluoride
2 dinitrogen trisulfide
3 phosphorus mononitride
4 silicon tetrabromide

Explanation:

Step1: Recall naming rules

Prefixes indicate number of atoms. "tetra -" means 4, "tri -" means 3, "mono -" means 1.

Step2: Determine formula for carbon tetrafluoride

Carbon is C, fluorine is F, and 4 fluorine atoms give $CF_4$.

Step3: Determine formula for dinitrogen trisulfide

Nitrogen is N, sulfur is S, 2 nitrogen and 3 sulfur atoms give $N_2S_3$.

Step4: Determine formula for phosphorus mononitride

Phosphorus is P, nitrogen is N, gives PN.

Step5: Determine formula for silicon tetrabromide

Silicon is Si, bromine is Br, 4 bromine atoms give $SiBr_4$.

Answer:

1. $CF_4$
2. $N_2S_3$
3. PN
4. $SiBr_4$
