A 200. mL sample of hydrogen chloride at 690 torr and 20. degree C is dissolved in 100.0 mL of water. The solution was titrated to the stoichiometric point with 15.7 mL of a sodium hydroxide solution. What is the molar concentration of the NaOH in the solution? Circle the statement that is false? The average kinetic energies of molecules from samples of different "ideal" gases are the same at the same temperature. The molecules of an ideal gas are relatively far apart. All molecules of an ideal gas have the same kinetic energy at constant temperature. Molecules of a gas undergo many collisions with each other and the container walls. Molecules of greater mass have a lower average speed than those of less mass at the same temperature. Describe when a gas behaves as a real gas instead of an ideal gas.
The molecules of an ideal gas are relatively very far apart on the average.
B.
At a given temperature, according to the kinetic molecular theory, the average velocity of He atoms is the same as the average velocity of F2 molecules.
C.
The average kinetic energies of molecules of samples of different ideal gases at the same temperature are the same.
D.
The molecules of a gas move in straight paths until they collide with other molecules or the walls of their containers, according to the kinetic molecular theory.
