tion:The First Law of Thermodynamics states that energy can be CONVERTED from ONE form to another with the interaction of HEAT, work and internal energy, but it cannot be created nor destroyed, under any circumstances. Mathematically, this is represented asΔU=Q+w(1)withΔU is the total change in internal energy of a system,q is the heat exchanged between a system and its surroundings, ANDW is the work done by or on the system.

lver nitrate (AgNO 3 ) reacts with sodium chloride (NaCl) a WHITE precipitate of SILVER chloride (AGCL) is formed which is highly insoluble in water, along with formation of sodium nitrate (NaNO 3 ).SINCE (AgCl) is insoluble in water it will precipitate out and (NaNO 3 ) is soluble in water so it will remain dissolved in the mixture. This reaction is an EXAMPLE of double displacement reaction and it occurs as follows:-AgNO 3 + NaCl→AgCl + NaNO 3
