Which of the chemical equations below are acid-base (proton transfer) reactions? select all that apply. mg(oh)2 (s) + h2so4 (aq) → mgso4 (s) + 2 h2o (l) fe(no3)3 (aq) + 3 koh (aq) → fe(oh)3 (s) + 3 kno3 (aq) zn (s) + cu(no3)2 (aq) → zn(no3)2 (aq) + cu (s) mg (s) + cu(no3)2 (aq) --> mg(no3)3 (aq) + cu (s) hcl (aq) + koh (aq) → kcl (aq) + h2o (l) nh3 (aq) + hcl (aq) → nh4cl (aq)?

There are three acid-base theories: Arrhenius, Bronsted-Lowry, and Lewis. Among the three, only the Bronsted-Lowry theory defines acids and bases based on the transfer of protons H⁺.

Mg(OH)₂ (s) + H₂SO₄ → MgSO₄ (s)  + 2 H₂O (l)

Fe(NO₃)₃ (aq) + 3 KOH (aq) → Fe(OH)₃ (s) + 3 KNO₃ (aq)

Zn (s) + Cu(NO₃)₂ (aq) → Zn(NO₃)₂ (aq) + Cu(s)

Mg (s) + Cu(NO₃)₂ (aq) → Mg(NO₃)₂ + Cu (s)

HCl (aq) + KOH (aq) → KCl (aq) + H₂O (l)

NH₃ (aq) + HCl (aq) → NH₄Cl (aq)

so what is the problem with your lab report and whats the subject of the lab report? i will you

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
