Question

Match the names of compounds with their chemical formulas:

A) Cobalt Sulfide - CoS
B) Cobalt Sulfite - CoSO3
C) Cobalt Sulfate - CoSO4
D) Cobalt Chloride - CoCl2

Answer 1

Cobalt Sulfide, Cobalt Sulfite, Cobalt Sulfate, and Cobalt Chloride correspond to CoS, CoSO3, CoSO4, and CoCl2, respectively. The formulas for germanium dioxide, carbon disulfide, and diselenium dibromide are GeO2, CS2, and SeBr2.

Step-by-step explanation:

To match each chemical name with its correct chemical formula:

• A) Cobalt Sulfide matches with CoS.
• B) Cobalt Sulfite matches with CoSO3.
• C) Cobalt Sulfate matches with CoSO4.
• D) Cobalt Chloride matches with CoCl2.

For the provided reference information:

1. Germanium dioxide is given by the formula GeO2.
2. Carbon disulfide is CS2.
3. Diselenium dibromide is Se2Br2, but it is generally written as SeBr2 because the prefix 'di' is understood in the compound's name due to the nonmetal nature of selenium.
