CH4(g)+2O2(g)->CO2(g)+2H2O(g) AH° < 0 Which of the following statements must be true for the combustion of CH4(g), represented by the equation above? 4CHE65 The bond dissociation energy between O atoms in O2 is greater than the sum of the bond dissociation energies of the two O - H bonds in H2O. The sum of the bond dissociation energies of the product molecules is equal to the sum of the bond dissociation energies of the reactant molecules. More bonds are formed in the products than are broken in the reactants. The sum of the bond dissociation energies of the product molecules is greater than the sum of the bond dissociation energies of the reactant molecules.

What is the maximum measured temperature in the Styrofoam cup? A 68.0 mL sample of 1.0 M NaOH is mixed with 44.0 mL of 1.0 M H2SO4 in a large Styrofoam coffee cup; the cup is fitted with a lid through which passes a calibrated thermometer. The temperature of each solution before mixing is 21.6°C. After adding the NaOH solution to the coffee cup, the mixed solutions are stirred until the reaction is complete. Assume that the density of the mixed solutions is 1.0 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g •°C), and that no heat is lost to the surroundings. The ΔHrxn for the neutralization of NaOH with H2SO4 is –114 kJ/mol H2SO4.

Question 1: Salman grows chilies in his 100 by 100 meters garden. He then sells the crop at the local farmers' market. Two seasons ago, he was able to produce and sell 1200 kg of chillies. Last season, he tried a new fertilizer that promised a 20% increase in yield. He harvested 1350kg of chillies. Did new fertilizer live up to its promise to get 20% increase in yield? Analyse and justify the answer. (10 marks)
