Question

3 multiple choice 20 points analyze the chemical formula to correcting identify the number of atoms that compromise the given compound. ag₂co₃ silver = 2 cobalt = 3 silver = 2 carbon = 3 oxygen = 3 silver = 2 carbon = 1 oxygen = 3 silver = 2 cobalt = 5

Explanation:

Step1: Analyze each element in the formula

In \(Ag_2CO_3\), \(Ag\) represents silver. The sub - script \(2\) indicates there are \(2\) silver atoms. \(C\) represents carbon. There is no sub - script for \(C\) (which is equivalent to a sub - script of \(1\)). \(O\) represents oxygen. The sub - script \(3\) indicates there are \(3\) oxygen atoms.

Step2: Check each option

• Option 1: \(Co\) is the symbol for cobalt, not present in \(Ag_2CO_3\).
• Option 2: Carbon has a sub - script of \(1\) (not \(3\)).
• Option 3: Silver (\(Ag\)) has \(2\) atoms, carbon (\(C\)) has \(1\) atom, and oxygen (\(O\)) has \(3\) atoms.
• Option 4: \(Co\) (cobalt) is not present in \(Ag_2CO_3\).

Answer:

Silver = 2, Carbon = 1, Oxygen = 3 (the third option)
