Identify the reaction type for each of the following. Briefly explain your answer. a) MnSO4 + H2S → MnS + H2SO4 b) H2SO4 + 2 NaOH → Na2SO4 + 2 H2O
Added by Angela R.
Step 1
- This reaction involves the exchange of ions between manganese sulfate (MnSO4) and hydrogen sulfide (H2S). The manganese ion (Mn²⁺) from MnSO4 combines with the sulfide ion (S²⁻) from H2S to form manganese sulfide (MnS), while the hydrogen ion (H⁺) from H2S Show more…

Write equations for each of the following. a. reaction of $\mathrm{H}_{2} \mathrm{~S}$ with $\mathrm{SO}_{2}$ b. oxidation of $\mathrm{SO}_{2}$ with $\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}(a q)$ to $\mathrm{SO}_{4}^{2-}$ C. reaction of hot, concentrated $\mathrm{H}_{2} \mathrm{SO}_{4}$ with $\mathrm{Cu}$ d. reaction of sulfur with $\mathrm{Na}_{2} \mathrm{SO}_{3}$
Classify each reaction in as many ways as possible. (a) $2 \mathrm{~K}(\mathrm{~s})+2 \mathrm{H}_{2} \mathrm{O}(l) \longrightarrow 2 \mathrm{KOH}(a q)+\mathrm{H}_{2}(g)$ (b) $2 \mathrm{KOH}(a q)+\mathrm{H}_{2} \mathrm{SO}_{4}(a q) \longrightarrow$ $$ \mathrm{K}_{2} \mathrm{SO}_{4}(a q)+2 \mathrm{H}_{2} \mathrm{O}(l) $$ (c) $\mathrm{Cu}(s)+2 \mathrm{H}_{2} \mathrm{SO}_{4}(l) \longrightarrow$ $\mathrm{CuSO}_{4}(a q)+\mathrm{SO}_{2}(g)+2 \mathrm{H}_{2} \mathrm{O}(l)$ (d) $\mathrm{NaBr}(\mathrm{s})+\mathrm{H}_{2} \mathrm{SO}_{4} \longrightarrow \mathrm{NaHSO}_{4}(a q)+\mathrm{HBr}(g)$
Which reactions are redox reactions? (a) $\quad \mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}(a q)+\mathrm{K}_{2} \mathrm{SO}_{4}(a q) \longrightarrow$ $\mathrm{BaSO}_{4}(s)+2 \mathrm{KNO}_{3}(a q)$ (b) $\mathrm{Ca}(s)+\mathrm{Cl}_{2}(g) \longrightarrow \mathrm{CaCl}_{2}(s)$ (c) $\mathrm{HCl}(a q)+\mathrm{NaOH}(a q) \longrightarrow \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{NaCl}(a q)$ (d) $\mathrm{Zn}(s)+\mathrm{Fe}^{2+}(a q) \longrightarrow \mathrm{Zn}^{2+}(a q)+\mathrm{Fe}(s)$
