Answer : The pH of a solution is, 7.28
Solution : Given,
Concentration of hydronium ion, 
= 
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
Therefore, the pH of a solution is, 7.28
Cloudy skies and precipitation. Rain is normally caused by water vapor within the condensation of the low pressure system.
Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.
It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
Cellular respiration uses glucose and oxygen to produce carbon dioxide and water, while the process of photosynthesis is used by plants and other photosynthetic organisms to produce energy.
