Which of the below statements a) through f) are true?

Question

Which of the below statements a) through f) are true?


For statements a) through d) use the following reaction:


Cu(s) + 2Ag+(aq) --> 2Ag(s) + Cu2+(aq)

a) Cu is the reducing agent

b) Ag+ is the reducing agent

c) Cu is oxidized

d) Ag+ is oxidized





e) HCl(g) + NH3(g) --> NH4Cl(s) is a redox reaction

f) 2CuCl(aq) --> CuCl2(aq) + Cu(s) is a redox reaction

Answer 1

a,c,f

Cu is oxidized thus it reduces Ag+, thus Cu is the reducing agent

b is false-Ag+ is the oxidizing agent
d is false- Ag+ is reduced
e) is false -it is acid-base reaction

Answer 2

a) oxidisation is loss, so Magnesium is a lowering agent, so this assertion is fake. b) SiCl4 has been decreased, so Silicon chloride is an oxidising, so this assertion is authentic. c) Oxidisation is loss, so magnesium is oxidised, so this assertion is authentic. d) The silicon in silicon chloride is decreased as alleviation is benefit, so this assertion is fake. e) it rather is fake a redox potential alleviation and oxidation on the comparable time, which for sure would not happen in ths case. f) it rather is fake as aluminiuim hydroxide has been decreased without something being oxidised.

Answer 3

b), c), and f) are true.
