Write the complete balanced equation for the reaction that occurs when calcium carbonate (caco3) reacts with lithium nitride (li3n) in an aqueous solution.

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.

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

The identities of substances are the same before and after which type of change
