A sample of neon gas has a pressure of 2.50 atm in a 2.50 L container, at what volume will neon have a pressure of 9.68?

What are some similarities of solids and gases?

What metric unit is used to measure distance?

In the chemical formula 3NO2 the number 3 is a

W (g) + X (g) - -> Y (g) + Z (g) Gases W and X react in a closed, rigid vessel to form gases Yand Z according to the equation above. The initial pressure of W (g) is 1.20 atm and that of X (g) is 1.60 atm. No Y (g) or Z (g) isinitially present.

In this process, a piece of paper with small holes in it separates a heterogeneous mixture by letting through the small particles and keeping out the big ones. That is called as
