Geetings In relation to chemical kinetics i was confused about how I can determine the characteristics/(explanation?) of a chemical reaction? for example: [tex]CaCO_3 + HCl -> CaCl_2 + CO_2 + H_2O?[/tex] 1.)amount of CO_2 heat evolved 2.) change in pH 3.)amount of CO_2 / volume CO_2 4.) Change in concentration of reactants 5.) Change in pressure 6.) change in conductivity I just dont actually get it... [tex]Mg + O_2 -> 2MgO[/tex] so the answer might be 1.) the amount of mass of Mg? hmmm What is the common technique in of determining these observations?
