Question

match the chemical name with the appropriate chemical formula
1 carbon tetrafluoride
2 dinitrogen trisulfide
3 phosphorus mononitride
4 silicon tetrabromide
5 iodine trichloride
6 disulfur trioxide
7 dichlorine heptoxide

Explanation:

Step1: Recall naming - compound rules

Prefixes in chemical names indicate the number of atoms of each element in the compound. "Tetra -" means 4, "tri -" means 3, "di -" means 2, "mono -" means 1.

Step2: Determine formula for carbon tetrafluoride

Carbon is C and fluorine is F. Carbon tetrafluoride has 1 carbon and 4 fluorines, so the formula is $CF_4$.

Step3: Determine formula for dinitrogen trisulfide

Nitrogen is N and sulfur is S. Dinitrogen trisulfide has 2 nitrogens and 3 sulfurs, so the formula is $N_2S_3$.

Step4: Determine formula for phosphorus mononitride

Phosphorus is P and nitrogen is N. Phosphorus mononitride has 1 phosphorus and 1 nitrogen, so the formula is $PN$.

Step5: Determine formula for silicon tetrabromide

Silicon is Si and bromine is Br. Silicon tetrabromide has 1 silicon and 4 bromines, so the formula is $SiBr_4$.

Step6: Determine formula for iodine trichloride

Iodine is I and chlorine is Cl. Iodine trichloride has 1 iodine and 3 chlorines, so the formula is $ICl_3$.

Step7: Determine formula for disulfur trioxide

Sulfur is S and oxygen is O. Disulfur trioxide has 2 sulfurs and 3 oxygens, so the formula is $S_2O_3$.

Step8: Determine formula for dichlorine heptoxide

Chlorine is Cl and oxygen is O. Dichlorine heptoxide has 2 chlorines and 7 oxygens, so the formula is $Cl_2O_7$.

Answer:

1. Carbon tetrafluoride - $CF_4$
2. Dinitrogen trisulfide - $N_2S_3$
3. Phosphorus mononitride - $PN$
4. Silicon tetrabromide - $SiBr_4$
5. Iodine trichloride - $ICl_3$
6. Disulfur trioxide - $S_2O_3$
7. Dichlorine heptoxide - $Cl_2O_7$
