A mixture of 2.10 * 10-3 g of O2, 3.88 * 10-3 mol of N2, and 5.25 * 1020 molecules of CO are placed into a vessel of volume 5.25 L at 12.5°C. a. Calculate the total pressure in the vessel. b. Calculate the mole fractions and partial pressures of each gas.

When the volume and number of particles of a gas are constant which of the following is also constant

How does a scientist the government? a. the scientist tells people in society what to do. b. the scientist determines the policies that the government spends money on. c. the scientist provides unbiased information to the government. d. the scientist makes laws based on his or her research results.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
