For the reaction 2Na+ 2H20 --> 2NaOH + H2, how many molecules of water are needed with 2.0 moles of sodium? Include the unit "molecules" in your answer.

What postulate of the kinetic molecular theory best explains why gases have high fluidity? because collisions between gas particles are elastic, there is no loss of energy as particles flow past each other. because gases consist of large numbers of tiny particles, they spread out and do not come in contact with each other. because the attractive forces between gas particles are negligible, gas particles can glide easily past one another. because the average kinetic energy of gas particles increases as temperature increases, gas particles behave more like a liquid. question 6 compare the compressibility of gases and liquids. support your answer by describing the arrangement of particles in gases and liquids.

What is the ph of a 0.0010 m hno3? 1.0 3.0 4.0 5.0

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
