Why is the water in the sealed chamber able to boil at room temperature? A. This sealed chamber is placed below sea level. O B. This sealed chamber is an open system, C. The vacuum pump is increasing the pressure inside the chamber. O D. The vacuum pump is reducing the pressure inside the chamber.

To calculate the molarity of a solution, you need to know the moles of solute and the

What role does weathering have in shaping earth’s surface? a) it allows sediments to fall out of a medium. b) it sediments settle on a new surface. c) it breaks down older material into sediments. d) it transports sediments to a different location. will give brainliest, answer quickly.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
