The number of particles that are in 12.7 moles of compound that Jessica had is 7.65 x10^24 particles of compound ( answer E)
<u><em>Calculation</em></u>
<u><em> </em></u>The number of particles are calculated using the Avogadro's Principle constant.
- that is according to Avogadro's 1 moles = 6.02 x10^23 particles
what about 12.7 moles of compound= ? particles\
by use of cross multiplication
- number of particles of compound= [12.7 moles x (6.02 x 10^23)] / 1 mole = 7.65 x 10^24 particles of compound ( answer E)
N.b moles and moles cancels each other
This problem can be solved by Dalton's law of partial pressures which states that <em>in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases</em>.
Ptotal = P₁ + P₂ + P₃ + ..... + Pn
Herein, Ptotal = P(Ne) + P(Ar) + P(He)
Ptotal = 1.25 atm, P(Ne) = 0.68 atm and P(Ar) = 0.35
So, P(He) = Ptotal - P(Ne) - P(Ar) = 1.25 - 0.68 - 0.35 = 0.22 atm
Answer:
a. Thermal energy in transit due to spatial temperature difference .
Explanation:
Heat transfer -
Heat transfer is the exchange of the thermal energy or heat in between any physical systems .
It is the flow of energy or any form of energy from one system to another .
Heat transfer is divided into various mechanism , one of which is the thermal .
The thermal energy is the transit due to the spacial temperature difference .
