Problem- Write balanced chemical equations for each of the following verbal descriptions. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.) (a) Vanadium oxytrichloride (VOCl3) is formed by the reaction of vanadium (III) chloride with oxygen. (b) Niobium(V) oxide is reduced to the metal with hydrogen gas. (c) Iron(III) ion in aqueous solution is reduced to iron(II) ion in the presence of zinc dust. (d) Niobium(V) chloride reacts with water to yield crystals of niobic acid (HNbO3).
As much detail as probable is really appreciated
