Question

part 2 (1 point) the average single and double n - o bond lengths are 136 pm and 122 pm, respectively. assuming these two structures were to make equal contributions to the observed bonding in hno₂, predict the n - o bond length. pm part 3 (1 point) do you think these two structures contribute equally to the observed molecular structure of hno₂? choose one: yes no no way to tell

Explanation:

Step1: Calculate average bond - length

Since the two structures make equal contributions, we use the formula for the average of two values. The formula for the average of two numbers $a$ and $b$ is $\frac{a + b}{2}$, where $a = 136$ pm and $b=122$ pm.
\[l=\frac{136 + 122}{2}\]

Step2: Simplify the expression

\[l=\frac{258}{2}=129\] pm

Answer:

Part 2: 129 pm
Part 3: No
