Ok I got it wrong I think but I'm too lazy to delete all my hard work soooo.... merry Christmas?
Molar masses of
C = 12.0107
H = 2.016
O = 15.999
Now what we gots tuh do is take the masses and add them together, but we have to add 2 carbons and 2 oxygens because we are trying to find the molar mass of the empirical formula. So...
2(12.0107)+2(2.016)+15.999
24.0214+4.032+15.999 = 44.0524
Now that we have the molar mass of the empirical formula, we divide the 252.22 by it.
252.22/44.0524 = 5.7254
72.0642+12.096+95.994
Answer:
E. just before it reaches the ground.
Explanation:
The "kinetic energy" refers to the energy<em> when an object moves or is in motion.</em> When the ball leaves the racket, it is considered to have a great amount of kinetic energy. However, this decreases as the ball reaches its maximum height, but the potential energy is at its highest. Upon falling down, its kinetic energy increases but its potential energy decreases.
<em>Provided that there's no air resistance,</em><em> the speed of falling is even faster for the ball because of gravity and nothing is slowing it down, </em>which means it will have a<u> maximum kinetic energy</u><u> just before it reaches the ground.</u>
Hydrazine and UDMH are both organic nonpolar liquids. Despite having different densities, their miscibility with each other allows the mixture of the two to homogenize. This means that the concentration of hydrazine and UDMH in all parts of the mixture are the same. This is also the reason why the mixture is called Aerozine 50 because the components are not distinguished but rather, stay well mixed in the system providing a stable set of properties unique to Aerozine 50.
