Click Hide Forces, and select the Oxygen/Oxygen option. On the potential energy diagram, zoom out until the entire graph is visible. Pull the atoms a short distance apart, release them, and observe what happens.
Select all the statements that correctly compare oxygen atoms to argon atoms.
The oxygen atoms are attracted to each other much more strongly than the argon atoms.
The oxygen atoms have much less potential energy than argon when they are together.
The oxygen atoms stay much closer to each other than the argon atoms.
The oxygen atoms vibrate less quickly than the argon atoms.

When a scientific theory has been tested and proved by the scientific community, it becomes a law

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.

Ascientist measures the speed of sound in a monatomic gas to be 449 m/s at 20∘c. what is the molar mass of this gas?
