Answer:
Carbon tetrachloride is non-polar and so the only kind of force that can exist is induced dipole.
Answer:
Here's what I find.
Explanation:
Many scientists contributed to our model of the atom.
Among those who received the Nobel Prize for their work are:
1906 — J.J. Thomson — discovery of the electron
1908 — Ernest Rutherford — nuclear model of the atom
1922 — Niels Bohr — planetary model of the atom
1922 — Albert Einstein — quantum mechanical model of the atom
1935 — James Chadwick — discovery of the neutron
The chemical equation for this reaction is this:
CO2 + 4H2 = CH4 + 2H2O
from the equation, the mole ration of CO2 to CH4 is ratio 1:1
and CH4 = 25.1
The mole ratio of H2 to H2O is 4:2
therefore, mole of H2 = 19.1* 4/2 = 38.2
The moles of methane produced is 38.2 moles
Something that scientists study that is cold could be liquid nitrogen!
Answer : The pOH of pure water is, 6.68
Explanation :
As we are given that:
First we have to calculate the concentration of hydroxide ion.
As,
As we know that in pure water the hydrogen ion and hydroxide ion concentration are equal. That means,
So,
Now we have to calculate the pOH.
Therefore, the pOH of pure water is, 6.68
