Molar mass of N2H4 = 32 grams/mole
<span>3.95 grams of N2H4 = 3.95/32
= 0.123 moles </span>
<span>This will produce 0.123 moles of N2 </span>
<span>Now,
From the gas law equation. </span>
<span>P.V = n x R x T </span>
<span>P = 1 atm (given)
V = </span><span>0.123</span><span> x 0.082057 x 295 </span>
<span>V = 2.97 Liters </span>
<span>Theoretical yield = 2.97 Liters.
Actual yield = 0.750 Liters </span>
percentage yield = (0.75/2.97) x 100 %
= 25.25 %
Well, the colder something is, the less the molecules move around, making it harder for the substance to move
think of it as this:
extremely hot water=steam/gas, moves quickly
room tempurature=liquid, moves slower than steam/gas
frozen=solid, moves very slowly, if even
the colder it is, the slower water moves
Answer:
An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion. An orbital can simply be defined as space or the region where the electron is likely to be found the most.
