Question

Any reaction that absorbs 150 kcal of energy can be classified as ____ endothermic exothermic activated redaction oxidation Which of the following is not part of the kinetic theory of gases? gas is composed of very small particles the particles of a gas are very far apart gas particles move rapidly gas particles do not attract or repel one another gas particles move faster when the temperature increases Which measurement describes the pressure of a gas? 315 K 1.2 gL 2.5 L T25 0.45 moles The gas with an initial of 24.0 L at a pressure of 565 is torr compressed until the volume 377 torr 760 torr 648 torr 500 torr 465 torr

Explanation / Answer

Q60

any reactions/system that abosrb heat, is ENDOTHERMIC

Q61.

kinetic theory states:

a) gases are small particles --> they ar econsidere infinitvely small, so they are not considered as "particles" ratehr point.

b) particles are far aaway

c) they move rapidly

d) they do not interact between each other

e) as T increase, they move faster

Q62.

pressure of a gas --> must have pressure units

K --> temperature

g/L = density

L = volume

mm Hg = pressure

moles = maount os fusbtance
