2. Calculate the partial pressure, in atmospheres, of Oz in the dry air outside an airliner cruising at an altitude of about 35000 ft (10670 m), where the
atmoshperic pressure is 181 mm Hg. How much must the outside air be
compressed to produce a cabin pressure in which the partial pressure of
Oz is 0.200 atm? In dry air, there are 0.2085 moles of Oz in every mole of air.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
