Chemistry Reactions and Formulas

Question

Part A. Tell whether the reaction will occur or not and why Part B. Write the balanced equation for those that will occur. Write the formulas of the reactants for those reactions that do not occur. Part C. Include the Physical States of Matter of both reactions #1. Silver sulfide plus hydrochloric acid #2. Bromine plus Sodium Chloride

Answer 1

1). Silver sulfide + hydrochloric acid. This reaction will not take place because silver is below hydrogen in the activity series (less reactive than hydrogen). Ag₂S(s) + 2HCl(aq) ==> no reaction

2). Bromine + sodium chloride. This reaction will not take place because bromine is less reactive than chlorine, so it will not displace the chlorine. Br₂(l) + 2NaCl(aq) ==> no reaction.
