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.
Is ammonium chloride (NH 4 Cl in case someone reads this and doesn't know the chemical formula) an ionic or molecular compound?'m leaning towards it being molecular because the difference in the electronegativity values of nitrogen and chlorine is .12. The reason for me to questions this is the ammonium ion would be fairly electron dense.
