Given the following chemical reaction: 202 ch4 co2 2 h20what mass of ch4 is required to completely react with 100 grams of o2?

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms

Which samples do the atoms have the least kinetic energy

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid
