Explanation:
It is given that r = 0.283 nm. As 1 nm = .
Hence, 0.283 nm =
- Formula for coulombic energy is as follows.
where, e = C
=
=
- As 1 eV =
So, 1 J =
Hence, U =
= 8.9 eV
- Also, 1 J =
= kJ/mol
Therefore, U = kJ/mol
=
The answer would be Thymine.
Hope this helps! (:
Using the relationship M1V1 = M2V2 where M1 and M2 are the molar concentrations (mol/L or mmol/ml) and V1 and V2 are the volumes of the solutions, we can arrive at the following answer for the given problem:
<span>15.0M (L of stock solution) = 2.35M (0.25L) *all volumes were converted to liters.
L of stock solution = (2.35*0.25)/15.0
Therefore, 0.0392L or 39.17 ml of stock solution is needed. </span>
Answer:
CCl4 is a covalent bonded nonpolar molecule.
Explanation:
Although there is an electronegativity (small) difference between C and Cl, its structure with 4 chlorine atoms allows the polarity to be "canceled out." I have attached a picture of the molecule below where you can clearly see the dipole movement on either side gets canceled hence making it have no net dipole movement. Additionally, CCl4 has a total number of valence electrons to be 32. 7 for one chlorine atom and 4 for a carbon one. The octets are satisfied as well. It's covalent because carbon and chlorine are nonmetals.
