Answer: The pH of the solution is 5.65
Explanation:
The relationship between the pH and the pOH is that .
Given this, we can plug in the pOH and subtract that from 14.
I hope this helped! Pls give brainliest!! :)
Answer:
K=1.93
Explanation:
Given reactions are:
A +2B ⇄ 2C K1=2.79
2C ⇄ D K2=0.186
D⇄ A+ 2B K=?
If we reverse the reaction then the euillibrium constant also become reciprocal of original value:
3rd reaction is a combination of reciprocal of 1st and 2nd reaction
2C⇄A +2B 1/K1;........................1
D ⇄ 2C 1/K2; ..............................2
On adding 1 and 2
D ⇄A +2B
K=1.93
It would be C because you would do m divided by s squared and you would get 0.11 but you would round it to 0.12
Answer:
The molar mass of the gas should be 43.0 g/mol.
Explanation:
1.Use the ideal gas law() & the formula for moles and molar mass().
2.Insert the equation into and re-arrange to solve for M(molar mass).
3.Insert values and use the gas constant R = since the volume is in liters and the pressure is in atmosphere units.
4. Your answer should be 42.99 g/mol or 43.0 g/mol.
Have fun with chemistry!
