Write the equations of chemical reactions HgO-O2-Al2O3
| August 5, 2021 | education
We need to write two equations of chemical reactions that correspond to these transformation chains
HgO —> O2 —> Al2O3.
The first chemical reaction: the mercury base unfolds. Mercury base – HgO.
HgO -> Hg + O2. This reaction must be leveled so that there is an equal amount of substance on the left and right sides.
2HgO -> 2Hg + O2.
The second reaction: the interaction of oxygen (valency 2) and aluminum (Al valency -3).
O2 + Al -> Al2O3.
Equalized reaction: 3O2 + 4Al -> 2Al2O3.
