H C C H Each carbon has only three covalent bonds instead of 4. 4) Consider the following reaction: H+ + Cl- HCl Name the reactants and products. Does the expression indicate reaction is reversible? H+ and Cl- are reactants, HCl is the product. Reaction is not reversible. 5) How can the freezing of water crack boulders?
