If 78.4 grams of aluminum metal react with excess hydrochloric acid, how many grams of hydrogen gas can be produced? 2al + 6hcl yields 2alcl3 + 3h2

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
