Question

Поставьте коэффициент в уравнениях: NO2+H20=HNO3 ; P+O2=P205 ; Al2S3+H2O=AL(OH)3+H2S

Answer 1

Первая реакция у тебя не правильная , правильно писать : 
4NO2+2H2O+O2=4HNO3
4P+5O2=2P2O5
Al2S3+6H2O=2Al(OH)3+3H2S

Answer 2

Balancing Chemical Equations

To balance the given chemical equations, we need to ensure that there are an equal number of each type of atom on both sides of the equation. Let's balance the equations provided:

1. Balancing the Equation: NO2 + H2O = HNO3 - The balanced equation is: 3 NO2 + H2O = 2 HNO3.

2. Balancing the Equation: P O2 = P2O5 - The balanced equation is: 4 P + 5 O2 = P4O10.

3. Balancing the Equation: Al2S3 + H2O = Al(OH)3 + H2S - The balanced equation is: Al2S3 + 6 H2O = 2 Al(OH)3 + 3 H2S.

These are the balanced chemical equations based on the given reactions.
