Question
Need help with making sure that answers to the following question is correct. Write a balanced equation for the reaction that occurs in each of the following cases: (a) Chlorine reacts with water. (b) Barium metal is heated in an atmosphere of hydrogen gas. (c) Lithium reacts with sulfur. (d) Flourine reacts with magnesium metal.Explanation / Answer
(a) Chlorine reacts with water See p 284 for this one: Cl2(g) + H2O(l) -----> HCl(aq) + HOCl(aq) (b) Barium metal is heated in an atmosphere of hydrogen gas Ba(s) + H2(g) ---> BaH2(s) Note the formation of the metal hydride - here H is a -1 anion. (c) Lithium reacts with sulfur Typical combination reaction between a metal and a nonmetal to form a salt.... 2Li(s) + S(s) --> Li2S(s) (d) Fluorine reacts with magnesium metal Again, metal + nonmetal --> salt; watch those charges! Mg(s) + F2(g) --> MgF2(s)
