Answer 2

Answer:

The values of a, b, x, and y are (2) 4, 5, 1, 3.

Explanation:

The balanced reactions are as follows:

Reaction 1: 2NH₃ + (5/2)O₂ → 2NO + 3H₂O

To get rid of the fraction, we multiply all the coefficients by 2. Therefore,

Reaction 1: 4NH₃ + 5O₂ → 4NO + 6H₂O

Comparing the balanced reaction with aNH₃ + bO₂ → cNO + dH₂O , we get a = 4 and b = 5.

Reaction 2: Fe₂O₃ + 3CO → 2Fe + 3CO₂

Comparing the balanced reaction with xFe₂O₃ + yCO → pFe + qCO₂ , we get x = 1 and y = 3.

Therefore, the values of a, b, x, and y are 4, 5, 1, and 3 respectively.
