    I need help with my science lab!!!! I have to apply stoichiometry for the theory part of my lab and also the properties of a metal. so basically what iím doing is that i have 5 different test tubes filled with 5mL of HCl and different quantities of Mg (so different amount of mass of magnesium) and i write down the temperature of the reaction every ten second also the test tube are noted 1 to 5 so from the smallest mass of Mg to the highest and each reaction became hot and the temperature kept rising but the more Mg there were the higher the temperature PLEASE HELP AS SOON AS POSSIBLE !! ITíS DUE SOON !
