Explain whether each of the possible reactions listed below will occur. For those that will, predict what the products will be.
Alex777 [14]

Answer:

Zn(s) + 2H₂O (l) → Zn(OH)2(aq) + H2(g)

Sn(s) + O2(g) →SnO2(s)

Cd(s) + Pb(NO3)2 (aq) →Cd(NO3)2 (aq) + Pb(s)

Cu (s) + HCl(aq) → can not occur

Explanation:

Metals reacts with liquid water to yield the corresponding metallic hydroxide and hydrogen gas as shown above; Zn(s) + 2H₂O (l) → Zn(OH)2(aq) + H2(g)

Tin reacts with oxygen to yield tin (IV) oxide. This is an oxidation reaction as shown; Sn(s) + O2(g) →SnO2(s)

The reaction between Cd and Pb(NO3)2 is a single replacement reaction. It is possible because Cd is above Pb in the electrochemical series. Hence the reaction occurs thus; Cd(s) + Pb(NO3)2 (aq) →Cd(NO3)2 (aq) + Pb(s)

Copper does not displace hydrogen from dilute acids (such as HCl) since copper is lower than hydrogen in the electrochemical series hence the reaction does  not occur.
