Question

Уравняйте. HCI+NAOH=NACI+H2O N2+H2=NH3 H2O=H2+O2 NO+O2=NO2 SO2+O2=SO3

Answer 1

HCI+NAOH=NACI+H2O
N2+3H2=2NH3
2H2O=2H2+O2
2NO+O2=2NO2
2SO2+O2=2SO3

Answer 2

HCI+NAOH=NACI+H2O

N2+3H2=2NH3

2H2O=2H2+O2

2NO+O2=2NO2

2SO2+O2=2SO3

Answer 3

To balance the chemical equations, we need to make sure that the number of atoms of each element is the same on both sides of the equation. Here are the balanced equations:

1. HCI + NAOH = NACI + H2O 2HCl + 2NaOH = 2NaCl + H2O

2. N2 + H2 = NH3 N2 + 3H2 = 2NH3

3. H2O = H2 + O2 2H2O = 2H2 + O2

4. NO + O2 = NO2 2NO + O2 = 2NO2

5. SO2 + O2 = SO3 2SO2 + O2 = 2SO3

The equations are now balanced with an equal number of atoms on both sides of the reaction arrow.
