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.
When the forces acting on an object have equal strength and act in opposite directions, they are balanced.When the forces acting on an object are unbalanced, they do not cancel out one another.
The answer is letter A. In most organisms cellular respiration usually involves oxygen to produce the most energy. Except in the process of fermentation, where the cells are deprived with oxygen causing it to form bacteria and other forms of organisms within the fermented sample.
