Answer:
2
Explanation:
K shell=2
L shell=4
Since carbon has an atomic no of 6 it electron shells are 2 namely kshell and lshell
Answer:
Molecules to moles is a one step conversion.
Explanation:
You need to understand the definition of a mole. It's basically 6.022x10^23 molecules, atoms, pencils, people, etc. it's like a dozen but a giant number. Having this in mind: 1mole=6.022x10^23
So it turns into a stoichiometry problem:
9.3x10^24 molecules (1 mole / 6.022 x 10^23 molecules) = your answer in moles.
A mixture is a compound of two or more substances a pure substance is only made of one kind of atom and a solution is composed of a liquid substance made of two or more types of atoms
I think you meant ![3.08*10x^{8}](https://tex.z-dn.net/?f=3.08%2A10x%5E%7B8%7D)
If you want to do that then you it will be 308
,
000
,
000
or if you meant 3 x 108 then it would literally just be 3 multiplied by 108 = 324
The amount of heat that could be removed by 20.0 g of ethyl chloride is 8.184 kJ.
<h3>How do we calculate required heat?</h3>
Required amount of heat which can be removed for the vaporization will be calculated as:
Q = (n)(ΔHv), where
- n = moles of ethyl chloride
- ΔHv = heat of vaporization = 26.4 kj/mol
Moles will be calculated as:
n = W/M, where
- W = given mass of ethyl chloride = 20g
- M = molar mass of ethyl chloride = 64.51 g/mol
n = 20 / 64.51 = 0.31 mol
On putting all these values in the above equation, we get
Q = (0.31)(26.4) = 8.184 kJ
Hence involved amount of heat is 8.184 kJ.
