(i) A sample of coal contains C = 89%; H = 9% and ash = 2%. The following data were obtained when the above coal was tested in a bomb calorimeter. Weight of coal burnt - 1.2 g Weight of water taken = 580 g Water equivalent = 2100 g Initial temperature - 24.2 C Final temperature 28.3 C Fuse wire correction 11.2 cal Acid correction = 45.3 cal Calculate the gross and net calorific value of the coal, assuming the latent heat of condensation of steam as 650 cal/g. (ii) How does a small piece of Steel attach to the Zinc container prevents the corrosion of Zinc
