Question

Осуществите пр-ия HgO=O2=CuO=Al2O3

Answer 1

2HgO=2Hg+O2
2Cu+O2=2CuO
3CuO+2Al=3Cu+Al2O3

Answer 2

Balancing the Chemical Equation

To balance the chemical equation HgO = O2 = CuO = Al2O3, we need to first separate the equations and balance them individually.

1. Balancing HgO = O2 - The balanced equation for the decomposition of mercury(II) oxide (HgO) into mercury and oxygen is: `2 HgO = 2 Hg + O2`.

2. Balancing O2 = CuO - The balanced equation for the formation of copper(II) oxide (CuO) from copper and oxygen is: `2 Cu + O2 = 2 CuO`.

3. Balancing CuO = Al2O3 - The balanced equation for the formation of aluminum oxide (Al2O3) from copper(II) oxide (CuO) and aluminum is: `2 Al + 3 CuO = Al2O3 + 3 Cu`.

Overall Balanced Equation

Combining these balanced equations, we get the overall balanced equation: `2 HgO = 2 Hg + O2 = 2 Cu + O2 = Al2O3 + 3 Cu`
