The boiling point of a liquid can be raised by adding pressure. Like wise, if you lower the pressure the boiling point goes down. This can be explained by the fact that boiling occurse when the vapor pressure equals the outside pressure so when the outside pressure rises the vapor pressure required for boiling also rises. Vapor pressure is proportional to temperature and therefore temperature needs to increase to make the vapor pressure increase.
I hope this helps. Let me know in the comments if anything is unclear or if you want me to explain anything further.
Chemical bonds hold atoms together to form compounds through the sharing of electrons or the transferring of electrons.
Bio is not my strongest subject, but I am pretty sure that a pyramid of numbers differs from an ecological pyramid because it displays the number of organisms at each trophic level
Answer:
Hydroxyl ion concentration is 
.
Explanation:
From the given,
pH of the solution = 11.30
pH+pOH = 14
11.30 + pOH = 14
pOH = 14-11.30 = 2.7
The pOH of the solution is 2.7
<u>Concentration of hydroxyl ion:</u>
![2.7= -log[OH^{-}]](https://tex.z-dn.net/?f=2.7%3D%20-log%5BOH%5E%7B-%7D%5D)
![log[OH^{-}]= -2.7=5.08\times10^{-11}M](https://tex.z-dn.net/?f=log%5BOH%5E%7B-%7D%5D%3D%20-2.7%3D5.08%5Ctimes10%5E%7B-11%7DM)
Therefore, hydroxylion concentration is .
