Answer: Natural gas is produced from onshore and offshore natural gas and oil wells and from coal beds.
Explanation:
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g
Answer:
6.4
Explanation: pH
+
pOH
=
14
So if
pH
=
7.6
then
pOH
=
14
−
pH
=
6.4
