Answer:
biomass is a plant of animal material used as fuel to produce electricity
Tidal power is energy harnessed by converting engery from tides
That's what I know so far and took notes on hope it helped:)
I think they are all incorrect honestly most of them are fake.
Do you answer is he proposed a genetic relationship between species
Answer:
There are
Explanation:
In this problem, we need to find the number of molecules in
mol of
.
The molar mass of
is ![6\times 12+1\times 6=78\ g/mol](https://tex.z-dn.net/?f=6%5Ctimes%2012%2B1%5Ctimes%206%3D78%5C%20g%2Fmol)
No of moles = mass/molar mass
We can find mass from above formula.
![m=n\times M\\\\m=8.437\times 10^{-2}\ mol\times 78\ g/mol\\\\m=6.58\ g](https://tex.z-dn.net/?f=m%3Dn%5Ctimes%20M%5C%5C%5C%5Cm%3D8.437%5Ctimes%2010%5E%7B-2%7D%5C%20mol%5Ctimes%2078%5C%20g%2Fmol%5C%5C%5C%5Cm%3D6.58%5C%20g)
Also,
No of moles = no of molecules/Avogadro number
![N=n\times N_A\\\\N=8.437\times 10^{-2}\times 6.023\times 10^{23}\\\\N=5.08\times 10^{22}\ \text{molecules}](https://tex.z-dn.net/?f=N%3Dn%5Ctimes%20N_A%5C%5C%5C%5CN%3D8.437%5Ctimes%2010%5E%7B-2%7D%5Ctimes%206.023%5Ctimes%2010%5E%7B23%7D%5C%5C%5C%5CN%3D5.08%5Ctimes%2010%5E%7B22%7D%5C%20%5Ctext%7Bmolecules%7D)
Hence, there are
The charge is a little negative
