1 Students perform several experiments recording the reactions in lab journals. The students write and balance the chemical equations for each reaction and include the state of matter notations for each compound. The equations are below. Equations from Experiments Experiment 1 MgO(s) + H2O(1) ► Mg(OH)2(aq) Experiment 2 4Fe(s) + 302(9) - 2Fe2O3(s) Experiment 3 SO3(g) + H2O(1) - H2SO4(aq) Which chemical involved in the student experiments is dissolved in water?
