You would convert from grams to
moles by using the molar mass of the substance. The answer is letter B. for
example, the molar mass Carbon dioxide is 44.01 g/mol. It means that for 1 mole
of carbon dioxide, it contains 44.01 grams of Carbon dioxide.

Answer:
The bigger the atom the lesser the ability of the atom to hold on to its valence electrons.
Explanation:
Atomic radius can be looked at as the distance between the nucleus and the outermost energy level. As an atom gets bigger, the outer shell gets further and further from the positive nucleus. this means that electrons that are in the outer energy level become less held (attracted) by the nucleus because of distance and shielding of the attractive forces by the electrons in the lower energy levels. This means that as an atom becomes bigger, its ability to hold on to its outer electrons lessens.
Answer:
C
Explanation:
Glass doesn't move freely until it is too hot and melts.
Answer:
B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.
