Log in here. . 5CO 2 (g) +Si 3 N 4 (s) 3SiO(s) +2N 2 *( red and blue lines straight big uphill tiny down hill blue is higher both start at 20 both end at 40 )*. We follow the same procedure for HCl, adding the enthalpy of formation for H (0.0) to to the enthalpy of formation of Cl (-167.4). Mg, on the other hand, is not soluble in water and must be weighed out accurately. 46 29
