Answer:

The pH of a solution is simply a measure of the concentration of hydrogen ions,

, which you'll often see referred to as hydronium cations,

More specifically, the pH of the solution is calculated using the negative log base

of the concentration of the hydronium cations.

Now, we use the negative log base

because the concentration of hydronium cations is usually significantly smaller than

As you know, every increase in the value of a log function corresponds to one order of magnitude.

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:

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

Step 1:

$2NO_{2}\rightarrow NO+O$ ...(equation 1)

Step 2:

$NO_{2}+O\rightarrow NO+O_{2}$ ...(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:

⇒ $NO_{2}+O\rightarrow NO+O_{2}$

Which wind blows cool air toward the sea at night ?

alexira [117]

Answer:

Land breeze is the wind that blows cool air from land towards sea at night.

Explanation:

Land breeze is a type of wind which is cool and blows towards sea. It occurs due to the difference in the temperature of water and land. At night, the lands cool quickly due to the removal of heat from it. So the air that is present on land is cool down and this air moves towards sea. So this breez is called land breeze because it moves from land.
