Correct answer is B
- An oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, it gets reduced. A reducing agent is a substance that causes reduction by losing electrons; therefore it gets oxidized.
- Common examples of oxidizing agents include halogens (such as chlorine and fluorine)
passing each gas through bromine water
passing each gas through dilute potassium permanganate solution
passing each gas through silver nitrate solution
treating each gas catalytically with excess hydrogen gas
Correct answer is C
Acetylene reacts with ammoniacal AgNO3 solution to form a white precipitate of silver acetylide (AgC-=Cag) but ethylene does not
barium chloride solution

both zinc and copper are metals
the sulphate radical and the zinc ion are divalent
zinc is more electropositive than copper
both zinc and copper form depositive ions in solution
zinc is a reducing agent
