Q 1: An aqueous solution of substance A contains 70% by mass of substance A. 100 kg of water was added to dilute the solution. Calculate the volume of the resulting solution (mg) and the mass ratio (3, 3,X) for each of substance A and water (w) m = 200 kg m3 = XA,1 = 0.7 XA3= Xw.10.3 Xw,3 = m2 = 100 kg of w Q2: Depending on the following reaction, which represents the oxidation of ammonia 4NO + 6H20 4NH3 + 502 If 50 kg of ammonia and 100kg of oxygen are fed to the reactor, determine the limiting reactant, the percentage by which the other reactant increases, the extent of the reaction (g) and the mass of NO produced (kg) if the reaction proceeds to
