Answer

Explanation:

Step1: Write the chemical - reaction equation

The reaction is (N_2 + O_2\rightarrow NO). According to the law of conservation of mass, the number of atoms of each element in the reactants must equal the number of atoms of the same element in the products.

Step2: Balance the equation

Let the number of (NO) molecules be (x). The reaction equation is (N_2+O_2\rightarrow xNO). For nitrogen atoms, we have (2) nitrogen atoms in (N_2), so in the products, (x) (the coefficient of (NO)) must satisfy that the number of nitrogen atoms is (2). For oxygen atoms, we have (2) oxygen atoms in (O_2), and in (xNO), the number of oxygen atoms is also (x). Since the number of nitrogen and oxygen atoms in the reactants is (2) each, the balanced equation is (N_2 + O_2\rightarrow2NO).
