if a gas under 2,39.4 Kpa of pressure has volume of 13L at 50 c and the temperature is decreased to -20 c while its pressure decreases to 220.3 Kpa What is the new volume ? HELP ME PLEASE WITH EXPLANATION ("LIKE SHOWIG WORK") 20 POINTS ? THIS IS HW BY THE WAY AS SOON AS POSIBLE

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
