Problem 7 (Q41 & Q49 in pp. 1148 & 1149 ofJewett/Serway's book) (a) When 1.00g of hydrogen combines with 8.00g of oxygen, roughly 9.00g of water will be formed. During this chemical reaction, 2.86x105 J of energy is released. (i) Is the mass of the water larger or smaller than the mass of the reactants? (ii) What is the difference in mass? (iii) Calculate the percentage of the starting mass that is transformed to the other forms of energy. (13) The net nuclear lsion reaction inside the Sun can be written as 41H > 4He + E. The rest energy of each hydrogen atom is 93 8.78 MeV, and the rest energy of the helium- 4 atom is 3,728.4 MeV. (i) Calculate the percentage of the starting mass that is transformed to the other forms of energy. (ii) Compare with the percentage of mass transformation above, how many times improvement
