Which of the following reactions will not occur as written? Which of the following reactions will not occur as written? Zn (s) + Pb(NO3)2 (aq) → Pb (s) + Zn(NO3)2 (aq) Co (s) + 2AgCl (aq) → 2Ag (s) + CoCl2 (aq) Co (s) + 2HI (aq) → H2 (g) + CoI2 (aq) Sn (s) + 2AgNO3 (aq) → 2Ag (s) + Sn(NO3)2 (aq) Mg (s) + Ca(OH)2 (aq) → Ca (s) + Mg(OH)2 (aq)

Solutions

Expert Solution

Mg is less reactive then Ca( according to reactivity series). So, it cannot displace Ca.

But as describe in the last equation it displaces Ca heence that reaction is not possible.

Mg(s) + Ca(OH)2(aq) = Ca(s) + Mg(OH)2(aq)

All other reaction are possible.
