Question

Расставьте коэффициенты. 4NH3+3O2=>2N2+6H2O, 4NH3+5O2=>4No+6H2O.

Answer 1

4×14+1×3+16×2= 2×14×2+6×1×2+16
4×14+1×3+5×16×2=4×16×0+6×1×2+16
вообще я не уверен но лучше это чем не чего

Answer 2

To balance the chemical equations, we need to ensure that the same number of each type of atom is present on both sides of the equation. Here are the balanced chemical equations for the given reactions:

1. 4NH3 + 3O2 => 2N2 + 6H2O

2. 4NH3 + 5O2 => 4NO + 6H2O

Explanation of balancing:

1. For the first equation:

   • There are 4 nitrogen atoms (N) on the left side (4NH3) and 2 nitrogen atoms (N2) on the right side, so we need to add a coefficient of 2 before N2: 4NH3 + 3O2 => 2N2 + 6H2O
   • There are 12 hydrogen atoms (H) on the left side (4NH3) and 6 hydrogen atoms (H2O) on the right side, which is already balanced.
   • There are 6 oxygen atoms (O) on the left side (3O2) and 6 oxygen atoms (H2O) on the right side, so they are already balanced.

2. For the second equation:

   • There are 4 nitrogen atoms (N) on the left side (4NH3) and 4 nitrogen atoms (NO) on the right side, so they are already balanced.
   • There are 12 hydrogen atoms (H) on the left side (4NH3) and 6 hydrogen atoms (H2O) on the right side, so we need to add a coefficient of 6 before H2O: 4NH3 + 5O2 => 4NO + 6H2O
   • There are 10 oxygen atoms (O) on the left side (5O2) and 10 oxygen atoms (NO and H2O) on the right side, so they are already balanced.

Final balanced equations:

1. 4NH3 + 3O2 => 2N2 + 6H2O

2. 4NH3 + 5O2 => 4NO + 6H2O
