Question

a group of high school chemistry students is practicing how to write molecular compound names and formulas. they are at
carbon tetrachloride
sulfur dioxide
dinitrogen monoxide
after comparing all of the answers, the students realized that some people had written different formulas for the same com
drag each formula into the correct box to indicate which formulas are correct and incorrect.

possible answers
cacl4 s2o2 no2 n2o so2 ccl4

Explanation:

Step1: Analyze carbon tetrachloride

Carbon is $\ce{C}$, chloride is $\ce{Cl}$, “tetra -” means 4. So formula is $\ce{CCl4}$ ($\ce{CaCl4}$ is wrong as $\ce{Ca}$ is calcium, not carbon).

Step2: Analyze sulfur dioxide

Sulfur is $\ce{S}$, oxygen is $\ce{O}$, “di -” means 2. So formula is $\ce{SO2}$ ($\ce{S2O2}$ is wrong as it should be one sulfur atom).

Step3: Analyze dinitrogen monoxide

Nitrogen is $\ce{N}$, oxygen is $\ce{O}$, “di -” (for nitrogen) means 2, “mono -” (for oxygen) means 1. So formula is $\ce{N2O}$ ($\ce{NO2}$ is wrong as it has 2 oxygen atoms but should have 1 for “monoxide”).

Answer:

• Correct Formula: $\ce{N2O}$, $\ce{SO2}$, $\ce{CCl4}$
• Incorrect Formula: $\ce{CaCl4}$, $\ce{S2O2}$, $\ce{NO2}$
