Fill in the blanks: The interactions between particles can be described by Coulomb's law: that is, the between two charges has the least effect on the forces between them. Additionally, in an atom, the distance between the valence elctrons and the nucleus, knonw as the , has the greatest effect on the force. Finally, as the atomic radius decreases, the increases.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

Sulfuric acid is a polyprotic acid. write balanced chemical equations for the sequence of reactions that sulfuric acid can undergo when it's dissolved in water.
