Question

how many manganese atoms are in the compound below? ba(mno₄)₂ remember, the 2 outside the parenthesis distributes to all the atoms inside the parenthesis.

Explanation:

Step1: Analyze the compound formula

The formula is \(Ba(MnO_4)_2\). The subscript outside the parentheses (\(2\)) distributes to each atom inside the parentheses.

Step2: Count the manganese atoms

Inside the parentheses, there is \(1\) \(Mn\) atom. When we distribute the subscript \(2\) (from \((MnO_4)_2\)), for \(Mn\) we have \(1\times2 = 2\) \(Mn\) atoms. The \(Ba\) atom is not part of the parenthesized group and doesn't affect the count of \(Mn\) atoms.

Answer:

\(2\)
