the answer is C i just took the test
Explanation:
2AgNO3 + Ni Right arrow. Ni(NO3)2 + 2Ag
Considering the activity series, the reaction that will occur is:
2 AgNO₃ + Ni ⇒ Ni(NO₃)₂ + 2 Ag
Let's consider the following activity series.
Al > Mn > Zn > Cr > Fe > Cd > Co > Ni > Sn > Pb > H > Sb > Bi > Cu > Ag > Pd >Hg > Pt
F > Cl > Br > I
Elements that are more active will displace elements that are less active.
According to it, we will predict which reactions can occur.
- 2 NaBr + I₂ ⇒ 2 NaI + Br₂
NO. I is less active than Br so it won't displace it from NaBr.
- 2 Fe + Al₂O₃ ⇒ 2 Al + Fe₂O₃
NO. Fe is less active than Al si it won't displace it from Al₂O₃.
- 2 AgNO₃ + Ni ⇒ Ni(NO₃)₂ + 2 Ag
YES. Ni is more active than Ag so the reaction will occur.
- Pb + Zn(C₂H₃O₂)₂ ⇒ Zn + Pb(C₂H₃O₂)₂
NO. Pb is less active than Zn so it won't displace it from Zn(C₂H₃O₂)₂.
Considering the activity series, the reaction that will occur is:
2 AgNO₃ + Ni ⇒ Ni(NO₃)₂ + 2 Ag
