Calculate the heat of neutralization by mixing 200ml of 0.1M H2SO4 and 200 ml of 0.2 M KOH if heat generated by the mixing is 2.3 KJ

 

The specific heats of iodine vapours and solid are 0.031 and 0.055 Cal/g respectively. If heat of sublimation of iodine is 24Cal/g at 200”C, What is its value at 250”C.
