A gas cylinder at a pressure of 4408 torr contains a mixture of N2, O2, and helium gases. If the partial pressure of N2 gas is 1520 torr and the partial pressure of helium is 25 torr, what is the partial pressure of O2?

P subscript 2 = 4408 - 1520 + 25

P subscript 2 = 4408 - 1545

P subscript 2 = 2863 torr

Partial Pressure for O2 = 2863 torr

Explanation:

In order to get the partial pressure for O2, you are expected to sum that of N2 and Helium then subtract it from the pressure of the gas cylinder

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

where's the following? you gotta add it to know what the choices are
