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}

What would diluting the vinegar do to the rate of a reaction between vinegar and sodium hydroxide? decrease the rate of reaction
GarryVolchara [31]
Vinegar is aceti acid diluted in water.

The reaction of vinegar with sodium hydroxide is:

CH3COOH + NaOH ---> CH3COONa + H2O

That is an acid-base reaction.

The speed of reaction is proportional to the concentrations of the reactants.

Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.

Answer: decrease the rate of reaction.
