If a bottle of oxygen with a pressure of 500 kPa with a volume of .30 L at 290 K has a temperature change to 370 K and the volume changed to 1.5 L because the bottle broke open and leaked into the bottles outer container, then what is the new Pressure of the oxygen? Remember the combined gas law equation. P1V1 / T1 = P2V2 / T2

a
.128 kPa
b
128 kPa
c
0 kPa
d
500 kPa Lp

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.

How does the strength of the electrostatic force between an electron and a proton compare to the strength of the gravitational force between them?
