1. Can you balance this equation: Al(s)+HCl(aq)3= AlCl3(aq)+H2(g)
2. what type of reaction is this?
3. what do the symbols indicate about the states of the products?



4. How can a table listing of metals in an activity series be useful for predicting whether a chemical reaction will occur?
5. Compare the energy required to break the bonds of the reactants and the energy released when products form in an exergonic reaction.

-any answers will be helpful, thanks. (:
