What is heat of displacement? When a more electropositive metal displaces a less electropositive metal from a solution of its salt, heat change occurs. The heat of displacement is the heat change when one mole of a metal is displaced from its salt solution by a more electropositive metal. The thermochemical reaction for the displacement reaction of copper by … [Read more...] about What is heat of displacement?

What is the heat of combustion?
What is the heat of combustion? What is the definition of enthalpy of combustion? Heat of Combustion:A fuel is a chemical substance that burns in oxygen to produce heat energy. Combustion is a chemical reaction between a fuel and oxygen to release heat. Combustion is always an exothermic reaction. The heat of combustion is the heat produced when one mole … [Read more...] about What is the heat of combustion?
What is the enthalpy of neutralization?
What is the enthalpy (heat) of neutralization? Neutralisation is the reaction between an acid and a base to form a salt and water. Some examples of neutralisation reaction are as follows.During neutralisation reaction, hydrogen ions from acid react with hydroxide ions from alkali to form water. H+(aq) + OH-(aq) → H2O(aq) Since water is formed during … [Read more...] about What is the enthalpy of neutralization?
What is heat of precipitation?
What is heat of precipitation? Heat of precipitation:When two aqueous solutions are added together and a precipitate is formed, this reaction is called a precipitation reaction or double decomposition. This reaction is used to prepare insoluble salts. The heat given out in a precipitation reaction is called the heat of precipitation. The heat of … [Read more...] about What is heat of precipitation?
