A mixture of gases includes helium, neon, argon and krypton. The partial pressures are as follows: Partial pressure, mm Hg
He 127
Ne 103
Ar 128
Kr120
Carbon dioxide gas is added to the mixture until the total pressure is 2.00 atm. What is the partial pressure
of carbon dioxide in the mixture? Round your answer to the nearest mm Hg without units.

Apiece of copper has a temperature of 75.6 0c. when the metal is placed in 100.0 grams of water at 19.1 0c, the temperature rises by 5.5 0c. what is the mass of the metal?

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
