Another hydride of sulfur is hydrogen sulfide, $\ce{H2S}$; it forms a sulfonium ion, $\ce{H3S+}$. State the types of bonds present in the sulfonium ion, $\ce{H3S+}$, and explain how these bonds are formed.

(i) In aqueous solution sulfuric acid transfers a proton to a water molecule, forming the hydroxonium ion, $\ce{H3O+}$. Annotate the structure of the hydroxonium ion to indicate the coordination bond. (ii) Write an equation for the reaction between excess…
