A rough & ready method involves memorising three numbers â 3, 5 and 8 â and the fact that 1 km in miles is approximately equal to the first of these numbers divided by the second, or alternatively the second divided by the third. That is: 1 km â 3/5 or 5/8 miles.
Ammonium chloride solutions with ammonia are used as buffer solutions. In paleontology, ammonium chloride vapor is deposited on fossils, where the substance forms a brilliant white, easily removed and fairly harmless and inert layer of tiny crystals.
The vast majority of reactions include two or more reactants that react to give one or more products. One simple example of a reaction in which two reactants produce a single product is the reaction of the acid, hydrochloric acid (HCl), and the base, ammonia (NH3). When these two reactants are mixed with one another the reaction produces ammonium chloride (NH4 Cl).
