Question

fill in the blank 12 points
match the chemical name with the appropriate chemical formula
1 carbon tetrafluoride answer pn
2 dinitrogen trisulfide answer co₂
3 phosphorus mononitride answer cl₂o₇
4 silicon tetrabromide answer sef₄
5 iodine trichloride answer p₂s₅

Explanation:

Step1: Recall naming - compound rules

Prefixes indicate the number of atoms of each element in a molecular compound.

Step2: Determine formula for carbon tetrafluoride

"Carbon" is C, "tetra -" means 4, "fluoride" is F, so formula is $CF_4$.

Step3: Determine formula for dinitrogen trisulfide

"Dinitrogen" means 2 N atoms, "trisulfide" means 3 S atoms, so formula is $N_2S_3$.

Step4: Determine formula for phosphorus mononitride

"Phosphorus" is P, "mononitride" means 1 N atom, so formula is $PN$.

Step5: Determine formula for silicon tetrabromide

"Silicon" is Si, "tetra -" means 4, "bromide" is Br, so formula is $SiBr_4$.

Step6: Determine formula for iodine trichloride

"Iodine" is I, "tri -" means 3, "chloride" is Cl, so formula is $ICl_3$.

Answer:

1. $CF_4$
2. $N_2S_3$
3. $PN$
4. $SiBr_4$
5. $ICl_3$
