Answer:
The pH of a solution with a (H+] = 0.80 M is 
Explanation:
As we know
pH = -[log H+]
Substituting the value of H+ ion concentration in the above equation, we get -
pH = -log [0.80]
pH ![= -[-0.096] = 0.096 = 9.6 e^{-2}](https://tex.z-dn.net/?f=%3D%20-%5B-0.096%5D%20%3D%200.096%20%20%3D%209.6%20e%5E%7B-2%7D)
First you have to tell people what are the choices
Answer:
Le'chetelliers principle states that when an external factor such as temperature and pressure is added to a system in equilibrium...the disequilibrium will shift so as to annul the effect
Explanation:
To know the cause of increase in pressure in the above equation ...
You should note 2 things
1. the number of moles of all gaseous elements on both side and 2. How change in temperature will affect the equilibrium....
There are 4 moles on the left and 2 on the right ..
making it 4 : 1
so...increase in temperature will shift the equilibrium to the favour the reaction with fewer molecules thereby shifting it right ...the reverse is the case as to decrease in temperature
however; increase in temperature ...if it's an endothermic reaction having a positive sign...tge equilibrium will shift to the right and there will be increase in K....the reverse also is the case as to an exothermic reaction where delta h is negative -ve
The answer is q= -20 hope this helps
I'm pretty sure it would be -87,036
