[05.01] which of the following best explains what happens when the kinetic energy of particles in a solid state increases?
they vibrate so quickly that the particles ionize and become plasma.
they vibrate so slowly that the particles are no longer held together, resulting in a gas.
they vibrate fast enough to overcome the forces of attraction holding them together and become a liquid.
they vibrate more slowly, causing the forces of attraction holding them together to increase, resulting in a liquid.

What is the mass of sodium in 3 moles of sodium chloride

What happens to isotopes that are unstable?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
