Answer:
Explanation:
Due to you know the velocity of the electron, the only thing that you need to do is used the Newtonian kinetic energy formula. The kinetic energy is defined as the work needed by motion body of a given mass to accelerate from rest to its know velocity:
![KE=1/2mv^2=[kg*(m/s)^2]=[J]](https://tex.z-dn.net/?f=KE%3D1%2F2mv%5E2%3D%5Bkg%2A%28m%2Fs%29%5E2%5D%3D%5BJ%5D)
Answer:
16
Explanation:
4 nitrogen (N) atoms and 12 (3×4) atoms in Hydrogen (H)
Total = 4 + 12 = 16 molecules
First you need to know Avogadro constant and then divide it with mile 9f silicon.
then you got answer
mark as brainliest please
Well...........thanks for posting anyway.
So in this equation, 3 oxygen will react with 1 ethylene.
then, you convert from 12.9 Liters to moles.
1 mole = 22.4 Liters of gas.
x moles = 12.9 liters
So, 22.4x = 12.9, which means that x = 12.9/22.4, and you get about 0.6, then you divide by 3 because you have 3 Oxygen, and you get about 0.2.
So, 0.2 moles of ethylene C2H4 can react with 12.9 liters of Oxygen Gas.
Hope this Helps :)
