Not sure about the number of significant figures; you can decide where to round, but I would probably say 0.075mol.

The decomposition of nitrogen dioxide is described by the following chemical equation:
kow [346]

Answer:

The balanced chemical equation will be "NO_{2}+O\rightarrow NO+O_{2}".

Explanation:

The given equation is:

2NO_{2}\rightarrow 2NO+O_{2}

<u>Step 1:</u>

<u></u>2NO_{2}\rightarrow NO+O...(equation 1)

<u>Step 2:</u>

<u></u>NO_{2}+O\rightarrow NO+O_{2}...(equation 2)

On adding "equation 1" and "equation 2", we get

⇒  NO_{2}+NO_{2}+O\rightarrow NO+O+NO+O_{2}

⇒  2NO_{2}\rightarrow 2NO+O_{2}

The second step:

⇒  NO_{2}+O\rightarrow NO+O_{2}

Use the periodic table and example bond table to answer the question.
lyudmila [28]

In keeping with the general trends, K-Br will have the smallest bond energy. The bond energy refers to the energy that keeps the atoms in a bond together.

<h3>What is bond energy?</h3>

Bond energy is the energy that is required to hold atoms together in a bond. This energy must also be supplied when the atoms are to be separated.

We have the bond energies of each of the bons in the question, we have to note that the the smallest value of bond energy is Na-Br hence in keeping with the general trends, K-Br will have the smallest bond energy.
