Explanation / Answer

3. Ca(s) + H2O

balanced,

Ca(s) + 2H2O(l) --> Ca(OH)2(s) + H2(g)

complete ionic,

Ca(s) + 2H2O(l) --> Ca(OH)2(s) + H2(g)

net-ionic,

Ca(s) + 2H2O(l) --> Ca(OH)2(s) + H2(g)

--

Flaming wood splint burnt with more intense flame in all the cases wherein the release of H2 has occurs, which agree with the reaction we wrote here.

Balanced equations

D. 1a AgNO3 + KI

balanced,

AgNO3(aq) + KI(aq) ---> AgI(s) + KNO3(aq)

complete ionic,

Ag+(aq) + NO3-(aq) + K+(aq) + I-(aq) ---> AgI(s) + K+(aq) + NO3-(aq)

net-ionic,

Ag+(aq) + I-(aq) ---> AgI(s)

C.

1. Cu(s) + AgNO3(aq)

Balanced,

Cu(s) + 2AgNO3(aq) --> Cu(NO3)2(aq) + 2Ag(s)

complete ionic,

Cu(s) + 2Ag+(aq) + 2NO3-(aq) --> Cu2+(aq) + 2NO3-aq) + 2Ag(s)

net-ionic,

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

--

2. Mg(s) + HCl

balanced,

Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g)

complete ionic,

Mg(s) + 2H+(aq) + 2Cl-(aq) --> Mg2+(aq) + 2Cl-(aq) + H2(g)

net-ionic,

Mg(s) + 2H+(aq) ---> Mg2+(aq) + H2(g)
