Answer:

Within the atmosphere, as altitude increases,

A.air pressure stays the same.

B.air becomes heavier.

C.air pressure decreases. The answer.

D.air pressure increases.

Explanation:

That's the question. AND Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. Hope that helps. This means the answer is C.

How many liters will 2.76 mol CO2 occupy?<br> 2.76 mol<br> II

This problem is providing information about the moles of carbon dioxide, 2.76 mol, and asks for the volume this amount takes up, turning out to be 61.8 L according to the Avogadro's law:

<h3>Avogadro's law:</h3><h3 />

In chemistry, gas laws are used to relate the behavior of gases by virtue of the their pressure, volume, temperature and moles; thus several gas laws exist for us to do so, however, we here focus on the Avogadro's law which relates the volume and moles when both temperature and pressure are held constant.

In such a way, since no information on the constant variables is given, we assume the mentioned carbon dioxide is at STP, (0 °C and 1 atm), which means that we can use the following equivalence statement derived from the ideal gas law (PV=nRT):

22.4 L = 1 mol

Hence, we calculate the required volume:

$2.76molCO_2*\frac{22.4L\ CO_2}{1molCO_2} =61.8L\ CO_2$
