Question

Consider the following chemical equation: NH3 + O2 → NO + H2O The equation is unbalanced. Which of the following is the correct balanced equation?
*NH3 + 2O2 → NO + 6H2O
*4NH3 + 5O2 → 4NO + H2O
*4NH3 + 5O2 → 4NO + 6H2O
*NH3 + 5O2 → NO + 6H2O

Answer 1

The right answer is 4 NH3 + 5 O2 --> 4 NO + 6 H2O.

In chemistry, an equation establishes what happened during a chemical reaction. On the left side of the equation, we place the reagents that were used for the experiment and on the right, the products obtained during the experiment. According to the principle of conservation of the mass (Lavoisier) during a chemical reaction, no atom disappears, none is created, they combine differently. In summary, you must have the same number of atoms of each element on the right as on the left of the equation. This is why a balance equation must always be balanced.

The simplest method is to balance an equation by the trial and error method.

Answer 2

The answer is 4NH3+502→4NO+6H20. I hope this helps
