A sample of Nitrogen gas at a pressure of 2.06 kPa occupies 0.250 L at 20.0°C. What volume will this gas sample occupy at 50.0°C and 3.09 kPa?

law of conservation of matter

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
