In the lab, you did several experiments with magnesium metal and hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas. Mg (s) + HCl (aq) ----> MgCl2 (aq) + H2 (g) balance equation Calculate q and Δ H in kJ, if 225 mg of magnesium metal are added to 100 mL aqueous hydrochloric acid initially at 25 0C. The final temperature of the mixture is 48.6 oC. Use the density and specific heat of water. (4 pts)
