Asample of argon gas is at a pressure of 1.725x10^4 kpa and a temperature of 24°c in a rigid 20 l tank. how many moles of argon does this tank contain? (show your work)

What material does not melt at any temperature

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l.s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?

Consider the story you just read. all but one of the choices below indicate that something is living.
