Question

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

Explanation:

1. Carbon tetrafluoride has 1 carbon atom and 4 fluorine atoms, so its formula is $CF_4$.
2. Dinitrogen trisulfide has 2 nitrogen atoms and 3 sulfur atoms, so its formula is $N_2S_3$.
3. Phosphorus mononitride has 1 phosphorus atom and 1 nitrogen atom, so its formula is $PN$.
4. Silicon tetrabromide has 1 silicon atom and 4 bromine atoms, so its formula is $SiBr_4$.

However, the options provided in the image seem incomplete. Based on the naming - formula rules:

• Carbon tetrafluoride: The prefix "tetra -" indicates 4, so for 1 carbon and 4 fluorines, the formula is $CF_4$.
• Dinitrogen trisulfide: "Di -" means 2 for nitrogen and "tri -" means 3 for sulfur, so the formula is $N_2S_3$.
• Phosphorus mononitride: "Mono -" for nitrogen (1 nitrogen) with 1 phosphorus gives $PN$.
• Silicon tetrabromide: "Tetra -" for bromine (4 bromines) with 1 silicon gives $SiBr_4$.

Answer:

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