Which coefficients are needed to correctly balance this equation? HgO­­­­→?O2+?Hg 2,1,2 2,3,1 3,2,2 1,3,1

To balance the chemical equation , we need to ensure that the number of atoms of each element is the same on both sides of the equation.1. **Count the atoms on each side:** - On the left side, we have 1 Hg and 1 O in HgO. - On the right side, we have O in and Hg as a separate element.2. **Balance the oxygen atoms:** - Since has 2 oxygen atoms, we need 2 HgO molecules to provide 2 oxygen atoms. This gives us: 3. **Check the mercury atoms:** - With 2 HgO molecules, we have 2 Hg atoms on the left, which balances with the 2 Hg atoms on the right.The balanced equation is: Thus, the coefficients needed are 2 for HgO, 1 for , and 2 for Hg. Therefore, the correct answer is:2, 1, 2
