What are the missing coefficients for the skeleton equation below?
Kruka [31]

Answer:

4, 3 , 2 and 6

Explanation:

The reaction equation is given as;

       NH₃  +  O₂   →    N₂   +   H₂O

Now, we need to balance the reaction equation;

     NH₃  +  O₂   →    N₂   +   H₂O

put the numbers a,b,c and d;

    aNH₃  +  bO₂   →    cN₂   +   dH₂O  

We need to balance the equation algebraically, ;

  Conserving N;

      a = 2c

   Conserving H;

      3a  = 2d

   Conserving O;

      2b  = d

Now, let c = 1, a = 2, d  = 3 and b  = \frac{3}{2}  

  multiply through by 2;

            a  = 4, b = 3, c  = 2 and d  = 6

Insert the parameters:

                  4NH₃  +  3O₂   →    2N₂   +   6H₂O

Answer:

You would put the 4 quantum numbers corresponding to the electrons being described above

Explanation:

Quantum numbers refer to electrons, so I'll assume you mean the electron number that would correspond with the atomic number of the element. Quantum numbers are basically like an address for electrons, giving us information about the location of an electron from most general to most specific.
