Question

Predict expected reaction, write balanced equation (including phases) for expected reactions:

1M HCL + Zn

1M HCL + Mg

1M HCL+CaO

1M HCL + Fe

1M HCL +AL

1M CH₃COOH +Zn

1M CH₃​COOH + Mg

1M CH₃​COOH + CaO

1MCH₃​COOH +Fe

1MCH₃​COOH +Al

Answer 1

HCl is a pretty strong acid so expect reaction for all

Zn(s) + HCl(aq) --> ZnCl2(aq) + H2(g)

balance

Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)

Q2.

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

balance

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

Q3.

this is now an oxide, so expect H2+ O to actually form water rather than H2 and O2 gaes

CaO(s) + HCl(aq) --> CaCl2(aq) + H2O(l)

CaO(s) + 2HCl(aq) --> CaCl2(aq) + H2O(l)

Q4.

similar to Mg and Zn

Fe(s) + HCl(aq) --> FeCl3(aq) + H2(g)

Fe(s) + 3HCl(aq) --> FeCl3(aq) + 3/2H2(g)

Q5.

similar to Q4

Al(s) + HCl(aq) --> AlCl3(aq) + H2(g)

Al(s) + 3HCl(aq) --> AlCl3(aq) + 3/2H2(g)

For acetic acid...

note that this is a weak acid, so expect no reaction
