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.

 

How much heat is produced when 4.50g methane gas is burnt in a constant pressure system.

 

Two mol of an ideal gas is expanded isothermally and reversibly at 300 K to twice the original volume. Calculate q, w, E, and H.

 

1.5 mol of a perfect gas at 300 K is compressed reversibly and isothermally from a pressure of 1.01x10^5 N m^2 to 5.05x106 Nm^2. Calculate the amount of work done.
