Solution: Based on Brønsted-Lowry theory, which of the following are acid-base reactions Choose all answers that apply:a. NH+ NH⇌ NH4+ NH2b. Zn(s) + 2HCl(aq) → H 2(g) + ZnCl2(aq)c. 2Cr(s) + 3Cl 2(g) → 2CrCl3(s)d. LiOH(aq) + HBr(aq) → H2O(l) + LiBr(aq)


Based on Brønsted-Lowry theory, which of the following are acid-base reactions 

Choose all answers that apply:

a. NH+ NH⇌ NH4+ NH2

b. Zn(s) + 2HCl(aq) → H 2(g) + ZnCl2(aq)

c. 2Cr(s) + 3Cl 2(g) → 2CrCl3(s)

d. LiOH(aq) + HBr(aq) → H2O(l) + LiBr(aq)


We are asked to identify the acid-base reactions based on the Brønsted-Lowry definition. 

According to Brønsted and Lowry, an acid was classified as a proton donor while a base was a proton acceptor. 

Bronsted-Lowry acid → proton (H+) donor

Bronsted-Lowry base → proton (H+) acceptor

So we look at each reaction and identify if there is a proton that has been transferred.
