Question

balance this equation _n₂ + _h₂ --> _nh₃

Explanation:

Step1: Balance nitrogen atoms

Let the coefficients be \(a\), \(b\), \(c\) for \(N_2\), \(H_2\), \(NH_3\) respectively. The equation is \(aN_2 + bH_2
ightarrow cNH_3\). For nitrogen, \(2a=c\).

Step2: Balance hydrogen atoms

For hydrogen, \(2b = 3c\). Substitute \(c = 2a\) into \(2b=3c\), we get \(2b=3\times(2a)\), so \(b = 3a\).

Step3: Choose \(a = 1\)

If \(a = 1\), then \(c=2\) and \(b = 3\). The balanced equation is \(1N_2+3H_2
ightarrow2NH_3\)
