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.
ammonia, NH3, is a gas found in smelling salts. It has no charge. It is very soluble. Ammonium is a positive ion, NH4+,it is part of a compound. In water NH3 dissolves and reacts with water to produce NH4OH, a base iodine is an element.It is diatomic, found as I2, t i a purple crystal at room temerature and a purple gas just bove that.mmonia, NH3, is a gas found in smelling salts.
