The combustion of 10.0 g of an unknown chemical with molar mass = 35.56 g/mol, raises the temperature of 600 mL of water by 25oC. Assuming all the energy released by the reaction is absorbed only by the water, determine the ∆Hcomb of Mg. Note: specific heat capacity H20 = 4.18 J/goC

Your answer should follow the format:

a) q of the water

b) mols of unknown materials

c) ΔHcomb of unknown material with units (2 marks)

An electrons position cannot be known precisely only it's probability of being in a certain location can be known
