WebChemical Reactions and Equations Exercise 10 Solution 1 (i) The substance 'X' is calcium oxide (lime). Its chemical formula is CaO. (ii) Calcium oxide reacts vigorously with water to form calcium hydroxide (slaked lime). Concept insight: The key to this answer is white washing. Recall the substance used for white washing and answer accordingly. WebSolution: (i) CH4 : Molecular weight of methane, CH4 = (1 x Atomic weight of carbon) + (4 x Atomic weight of hydrogen) = [1 (12.011 u) +4 (1.008u)] = 12.011u + 4.032 u = 16.043 u (ii) H2O : Molecular weight of water, H2O = (2 x Atomic weight of hydrogen) + (1 x Atomic weight of oxygen) = [2 (1.0084) + 1 (16.00 u)] = 2.016 u +16.00 u = 18.016u
