Explanation:

Step1: Analyze the formula for Ba atoms

The formula is \(Ba(HCO_3)_2\). The coefficient of \(Ba\) is \(1\), so there is \(1\) \(Ba\) atom.

Step2: Analyze the formula for H atoms

In \(HCO_3\), there is \(1\) \(H\) atom. Since the \(HCO_3\) group is multiplied by \(2\) (from the subscript outside the parentheses), the number of \(H\) atoms is \(1\times2 = 2\).

Step3: Analyze the formula for C atoms

In \(HCO_3\), there is \(1\) \(C\) atom. With the \(HCO_3\) group multiplied by \(2\), the number of \(C\) atoms is \(1\times2=2\).

Step4: Analyze the formula for O atoms

In \(HCO_3\), there are \(3\) \(O\) atoms. With the \(HCO_3\) group multiplied by \(2\), the number of \(O\) atoms is \(3\times2 = 6\).

Answer:

\(1,2,2,6\)
