Answer:
19 protons, 20 neutrons and 18 electrons. i think
Explanation:
The correct answer is C. Dr Smith, who measures 13.5 g/mL on e2020.
Data:
p = 1 atm
V = 10 m * 8 m * 5 m = 400 m^3 = 400,000 liter
To = 0 + 273.15K = 273.15K
Tf = 20 + 273.15K = 293.15K
No - Nf =?
2) Formula
pV = NRT => N = pV / (RT)
3) solution
No = pV / (RTo)
Nf = pV / (RTf)
=> No - Nf = [pv / R] [ 1 / To - 1 / Tf ]
=> No - Nf = [1atm*400,000liter / 0.0821 atm*liter/K*mol ] [ 1 / 273.15 - 1 / 293.15]
No - Nf = 1216.9 moles ≈ 1217 moles
Answer: 1217 moles
Answer:
Nuclear fission is almost 5 times times more efficient than traditional fossil fuels at producing energy. That's a lot of energy packed into a small space. Nuclear energy is more efficient, which means it uses less fuel to power the plant and produces less waste.
Explanation:
H3C-CH2-CH2-CH3
<span>ion-ion bonds: not an ion </span>
<span>ion-dipole bonds: not an ion and no dipole </span>
<span>dipole-dipole bonds: butane is nonpolar, so no dipole </span>
<span>Hydrogen bonds: does not contain H bonded to F,O, or N </span>
<span>therefore the only intra-molecular bonds remaining are the weakest of the weak - london dispersion forces (aka Van Der Waals). These are randomly induced dipole attractions that happen when the electrons that move around randomly just happen to have a higher concentration at one end of the molecule. This causes dipoles to form in adjacent molecules, which induce dipoles in molecules next to them. these forces are very weak, but still play a part in raising the boiling point of butane.</span>
