Heat of combustion is the amount of heat evolved when the number of moles as represented by the balanced equation have been completely oxidised.

The amount of heat absorbed when a substance melts ………

The amount of heat evolved when 0.50 mole of HCl is mixed with 0.30 mole of NaOH solution is

Write a balance equation for the complete combustion of ethene

Heat of reaction is defined as the amount of heat absorbed or evolved at a given temperaturewhen the reactants have combined to form the products is represented by a balanced chemcial equation. If the heat is denofed by q then the numerical value of q depends on the manner in which the reaction is performed for the two methods of conducting chemical reactions in calorimeters. Constant volume W = 0 and q_(v) = Delta E Bomb calorimeter Constant pressure W = - V Delta P, therefore q_(P) = Delta E + P Delta V rar (V. Delta P) The heat of combustion of maltose at constant volume in the above question if water vapour are not condensed

Delta P) When maltose C_(12)H_(22)O_(11)(s) burns in a calorimetric bomb at 298 K yielding carbon dioxide and water, the heat of combustion is -1350 kcal/mol, the heat of combustion of maltose at constant pressure will be

The amount of heat released when a substance changes from gas to liquid ……………

Write the balanced chemical equations when hypophosphorus acid is heated.

The amount of heat liberated when one mole of NH_(4)OH reacts with one mole of HCl is

The total amount of heat evolved or absorbed in a reaction depends upon the number of steps in which the reaction takes place.
