Complete these Brønsted-Lowry reactions:

HSO4- + H+ <-->

HSO4- +OH- <-->

Can't you just add them?

HSO4- + H+ ==> H2SO4
HSO4- + OH- ==> H2O + SO4^2-

To complete the reactions, let's first write the balanced chemical equations for each of them:

1. HSO4- + H+ ⇌ H2SO4

2. HSO4- + OH- ⇌ SO4^2- + H2O

Now let's break down the reactions step-by-step:

1. HSO4- + H+ ⇌ H2SO4
In this reaction, the HSO4- ion (hydrogen sulfate ion) is acting as a base as it accepts a proton (H+) from an acid. As a result, the HSO4- ion forms sulfuric acid (H2SO4). This reaction can go forwards (from left to right) and backwards (from right to left), meaning it is a reversible reaction.

2. HSO4- + OH- ⇌ SO4^2- + H2O
In this reaction, the HSO4- ion (hydrogen sulfate ion) is acting as an acid as it donates a proton (H+) to a hydroxide ion (OH-) acting as a base. This results in the formation of sulfate ion (SO4^2-) and water (H2O). Similar to the previous reaction, this reaction is also reversible.

So, these are the completed Brønsted-Lowry reactions:

1. HSO4- + H+ ⇌ H2SO4

2. HSO4- + OH- ⇌ SO4^2- + H2O

To complete the Brønsted-Lowry reactions, we need to identify the acid and base involved in each reaction.

For the first reaction:
HSO4- + H+ <-->

In this reaction, the HSO4- ion is acting as an acid because it can donate a proton (H+). The H+ ion is acting as a base because it can accept a proton. Therefore, the HSO4- ion is the acid and the H+ ion is the base.

To complete the reaction, we simply combine the acid and base together:
HSO4- + H+ <--> H2SO4

The reaction is now complete, where H2SO4 is the final product.

For the second reaction:
HSO4- + OH- <-->

In this reaction, the HSO4- ion is still acting as an acid, as it can donate a proton. The OH- ion is acting as a base, as it can accept a proton. Therefore, the HSO4- ion is the acid, and the OH- ion is the base.

To complete the reaction, we combine the acid and base together:
HSO4- + OH- <--> H2O + SO4^2-

The reaction is now complete, yielding water (H2O) and sulfate ion (SO4^2-) as the final products.
