Answer:
pH = 3.65
Explanation:
given data
pKa of HNO2 = 3.40
nitrous acid (HNO2) = 0.110 M
NaNO2 = 0.200 M
to find out
What is the pH
solution
we get here ph for acidic buffer that is express as
pH = pKa + log(salt÷acid) ........................1
put here value and we get
pH = 3.40 + log(0.200÷0.110)
pH = 3.65
Explanation:
Wind helps to get out molecules of water from clothes.
In summer Ball is hard b because due to heat kinetic energy of molecules increases
N=m/M
n=118/58.93=2
Answer: 2 moles
