Write an equation that represents the reaction of $\text{NaCl}(s)$ with concentrated sulfuric acid.
Give the name of this reaction type.
At room temperature, $\text{NaI}(s)$ reacts with concentrated sulfuric acid and gives steamy fumes. Identify the substance responsible for those fumes.
As the reaction of $\text{NaI}(s)$ with concentrated sulfuric acid continues, several more products are formed, including a dark grey solid. Identify the chemical that produces the dark grey solid and name one other product from this further reaction.
Explain why the observations at room temperature are different when $\text{NaI}(s)$ reacts with concentrated sulfuric acid compared with $\text{NaCl}(s)$.
Complete the equation for the reaction between $\text{Br}^-$ and excess concentrated $\text{H}_2\text{SO}_4$ at room temperature. $\ldots \text{Br}^- + \ldots \text{H}^+ + \ldots \text{H}_2\text{SO}_4 \rightarrow \ldots$
