Heat of reactions

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

Define heat of reaction   The heat change when the number of moles of reactants indicated in the balanced equation react completely  
Define heat of combustion   The heat change when one mole of a substance is burned completely in excess oxygen  
What apparatus is used to measure heat of combustion?   Bomb calorimeter  
What is a kilogram calorific value?   The heat energy of the fuel produced when one kilogram of it is burned completely in excess oxygen  
What is bond energy?   The average energy required to break one mole of a particular covalent bond and to completely separate the neutral atoms  
Define heat of neutralisation   The heat change when one mole of H+ ions react with one mole of OH- ions  
Give an equation for heat given out   Mass*specific heat capacity*rise in temperature  
Define heat of formation   The heat energy given out when one mole of the reactants react with eachother to form a new compound  
What is Hess's law   The sum of heat changes if a reaction takes place in stages is equal to that if it had taken place continuously  
Law of conservation of energy   Energy cannot be created not destroyed only changed from one form to another
