Final answer:
a. S₂Cl2 is an inorganic compound. b. C₂H6O2 is an organic compound.
Step-by-step explanation:
a. A Each molecule of sulfur monochloride has two sulfur atoms and two chlorine atoms. Because it does not contain mostly carbon and hydrogen, it is an inorganic compound. B Sulfur lies to the left of chlorine in the periodic table, so it is written first in the formula. Adding subscripts gives the molecular formula S₂Cl2.
b. A Counting the atoms in ethylene glycol, we get six hydrogen atoms, two carbon atoms, and two oxygen atoms per molecule. The compound consists mostly of carbon and hydrogen atoms, so it is organic. B As with all organic compounds, C and H are written first in the molecular formula. Adding appropriate subscripts gives the molecular formula C₂H6O2.
To match the given symbols or molecular formulas to the correct terms, we can identify each substance and then categorize it based on its components and structure. Starting with SO₂, this is sulfur dioxide, consisting of one sulfur and two oxygen atoms, making it an inorganic compound. The symbol k represents the element potassium, therefore it's classified as an element. Cl₂ is chlorine gas, a diatomic molecule made of two chlorine atoms, making it an inorganic elemental molecule. Lastly, C₆H₆ is benzene, a hydrocarbon consisting of six carbon and six hydrogen atoms, and is categorized as an organic compound.
SO₂ - d. inorganic compound-
k - a. element-
Cl₂ - c. inorganic elemental molecule-
C₆H₆ - b. organic compound-
