H, I think. The oil has a lower density than the water, so after the 3 minutes it would float on top of the water.
<span>PV = nRT
moles of H2 = 1/2 = 0.5
moles of He = 1/4 =0.25
T = 273 + 27
partial pressure of H2
Px1 = 0.5x0.083x300
P=12.45 atmospheres
PP of He
px1 = 0.25x0.083x300
P =6 22 atmospheres
Totla pressure = 6.22 + 12.45 = 18.68 atm</span>
The state of matter which has the most orderly arrangement is solid. Here is the order of the three basic states of matter arranged from fastest to slowest, it's better to memorize it :<span>gas, liquid, solid. Also, remember that the colder your solid is, the more ordered it is.</span>
