18-9. Write balanced net ionic equations for the following reactions. Supply H^+ and/or H_(2)O as needed to ob- tain balance. ( MnO_(4)^-+VO^2+arrow Mn^2++V(OH)_(4)^+ (b) I_(2)+H_(2)S(g)arrow I^-+S(s) Cr_(2)O_(7)^2-+U^4+arrow Cr^3++UO_(2)^2+ ( Cl^-+MnO_(2)(s)arrow Cl_(2)(g)+Mn^2+ IO_(3)^-+I^-arrow I_(2)(aq) HPO_(3)^2-+MnO_(4)^-+OH^-arrow PO_(4)^3-+MnO_(4)^2- SCN^-+BrO_(3)^-arrow Br^-+SO_(4)^2-+HCN MnO_(4)^-+Mn^2++OH^-arrow MnO_(2)(s)

Let's correct and balance the net ionic equations step by step:(a) \( MnO_{4}^{-} + 5VO^{2+} + 8H^{+} \rightarrow Mn^{2+} + 5V(OH)_{4}^{+} \)(b) \( I_{2} + H_{2}S(g) \rightarrow 2I^{-} + S(s) \)(c) (d) \( 4Cl^{-} + MnO_{2}(s) + 4H^{+} \rightarrow Cl_{2}(g) + Mn^{2+} + 2H_{2}O \)(e) \( IO_{3}^{-} + 5I^{-} + 6H^{+} \rightarrow 3I_{2}(aq) + 3H_{2}O \)(f) (g) (h) \( 2MnO_{4}^{-} + 3Mn^{2+} + 4H_{2}O \rightarrow 5MnO_{2}(s) + 8OH^{-} \)These equations are now balanced with the inclusion of and as needed.
