Question

1 multiple choice 20 points which coefficients will balance the chemical equation below. n₂ + f₂ → nf₃ 3,2,1 no coefficients will balance this equation. 2,2,2 1,3,2

Explanation:

Step1: Balance nitrogen atoms

Let the coefficients be \(a\), \(b\), \(c\) for \(N_2\), \(F_2\), \(NF_3\) respectively. The chemical equation is \(aN_2 + bF_2
ightarrow cNF_3\). For nitrogen atoms: \(2a=c\).

Step2: Balance fluorine atoms

For fluorine atoms: \(2b = 3c\).

Step3: Substitute and find coefficients

Let's assume \(a = 1\), then \(c=2\) (from \(2a=c\)). Substitute \(c = 2\) into \(2b=3c\), we get \(2b=3\times2\), so \(b = 3\).

Answer:

1,3,2
