Answer:
2 Cu2S + 3 O2 = 2 Cu2O + 2 SO2
Explanation:
2 Cu2S + 3 O2 = 2 Cu2O + 2 SO2

Ba(OH)2 is an basic solution. It has more OH- ions than H+ ions. pOH should be calculated to find out its pH
The reaction is
Ba(OH)2 ⇒ Ba2+ (aq) + 2 OH-(aq)
One mole barium hydroxide releases 2 moles hydroxide ions.
Use that ratio to calculate molarity (M) of OH- ions [OH-]. The ratio is 1:2.
0.10 M Ba(OH)2 release 2*0.10 M= 0.02 M OH- ions
[OH-]= 0.02
pOH= - log [OH-] = - log 0.02 = 1.7
Thats not the answer! We found pOH of the solution before titration.
pH and pOH relationship is shown by formula of pH+pOH= 14
pH= 14-pOH
pH= 14-1.7= 12.3

Explanation:
It is absurd. Environmentalists prefer that you don’t recycle at all because most if not all of our recyclables are being recycled incorrectly.
