Question

H2O → H2 + O2; HgO - Hg + O2. расставить коэффициенты, срочно!!!!!

Answer 1

Ответ:

2Н2О=2Н2+ О2; 2НgO= 2Hg + O2

просто уравниваешь чтобы и в правой и в левой части было одинаково

Answer 2

Balancing Chemical Equations

To balance the chemical equations provided, we need to ensure that the same number of each type of atom is present on both sides of the equation.

Balanced Chemical Equations: 1. H2O → H2 + O2 2. HgO → Hg + O2

Balancing the Equations

1. For the first equation, we need to balance the number of oxygen atoms first. We can achieve this by placing a coefficient of 2 in front of H2O: - 2H2O → 2H2 + O2 Now, the oxygen atoms are balanced, but we need to balance the hydrogen atoms. We can do this by placing a coefficient of 2 in front of H2: - 2H2O → 4H2 + O2

The equation is now balanced.

2. For the second equation, we can balance the equation by placing a coefficient of 2 in front of HgO: - 2HgO → 2Hg + O2

The equation is now balanced.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
