A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.9kPa. If Po2= 6.6kPa and Pn2=23.0 kPa, what is Pco2?

The partial pressure of the carbon dioxide is 3,3 kPa.

Explanation:

We apply Dalton's law, according to which the sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of this:

Ptotal = P N2 + P C02 + P 02

32, 9 kPa= 23, 0 kPa + P C02 + 6, 6Kpa

P C02= 32, 9 kPa - 23, 0 kPa - 6, 6Kpa= 3, 3 kPa

they are made of gases.

they have a spherical shape.

they make energy through fusion.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
