g Ammonia gas (NH3) reacts with hydrochlorix acid (HCl) to form ammonium chloride (NH4Cl). If 3.0 g of ammonia react with 5.0 g of hydrochloric acid, what is the limiting reactant and how much ammonium chloride should be produced

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
