Dry air is 78.08% nitrogen, 20.95% oxygen and 0.93% argon with the 0.04% being other gases. if the atmospheric pressure is 760.0
sveticcg [70]
Partial pressure (N2) = mole fraction * total pressure
 
{    1 mole of any ideal gas occupy same volume of 1 mole of any other ideal gas under same condition of temperature and pressure so mole fraction in the sample is simply 78.08%   =   0.7808   this is because equal volume of each gas has equal moles

partial pressure N2 = 0.7808 * 760 .0
partial pressure =  593.4 mmhg    (   1 torr = 1mmhg  )

PLZ HELP!!

A and B are experiencing winter. The picture which isn't available here in this question is attached below.

Option C.

<h3><u>Explanation:</u></h3>

The earth is tilt by an angle of 23.2° to the vertical plane. This makes the seasonal variation of earth, because in some time of the year, the northern hemisphere faces the sun directly, experiencing summer and then southern hemisphere is away from summer experiencing winter and vice versa. The summer occurs when the place directly faces the sun. And the winter happens when the place obliquely faces the sun or doesn't face the sun at all.

Here in this diagram, we can see that the points A and B are the north pole and the part in northern hemisphere respectively which aren't facing the sun directly, whereas C and D are facing the sun. Thus the southern hemisphere is experiencing summer and the northern hemisphere the winter.

Propane (c3h8) is burned in oxygen to produce carbon dioxide and water. the heat of combustion of propane is -2012 kj/mole. how
Olegator [25]
C_{3} H_{8} + 5 O_{2} ---\ \textgreater \  3CO_{2}  +4H_{2}O    (-2012 \frac{kJ}{mol} )&#10;&#10;&#10;3 mol                10 mol&#10;&#10;&#10;C_{3}H_{8} is /excess /reactant&#10;&#10;because 3 mol propane require 15 mol oxygen (by reaction)&#10;&#10;5 mol oxygen ---1 mol propane, so&#10;&#10;10 mol oxygen ---2 mol propane&#10;&#10;Only 2 mole propane will be burned,&#10;&#10;so &#10;&#10;2012 ( kJ/mol)*2 mol =4024 KJ heat will be given off&#10;&#10;Correct answer is number 4.&#10;&#10;&#10;
