Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents (argon has the European food additive code E938). The predominance of radiogenic 40Ar is the reason the standard atomic weight of terrestrial argon is greater than that of the next element, potassium, a fact that was puzzling when argon was discovered. 5 points) What is Var( X 12)? Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. Moles is equal to wait, divided by more no mas substituting in the values. It is also used when air must be excluded to prevent oxidation of hot metals, as in welding aluminium and the production of titanium to exclude air. Characteristics A small piece of rapidly melting solid argon Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. In a solid, the forces between particles are strong enough to hold them in place.In a liquid, particles are very nearly as close to each other as they are in a solid, but those positions keep changing and the individual particles are free to move around.In a gas, there is a great deal of space between particles.
