Answer:
tetrahedral
Step-by-step explanation:
According to the valence shell electron pair repulsion theory (VSEPR) the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule.
The predicted electron pair geometry may sometimes differ from the molecular geometry due to the presence of lone pairs and multiple bonds.
If we consider each nitrogen atom in N2 independently, we will notice that each nitrogen atom has four regions of electron density. Hence the electron pair geometry is tetrahedral.
Answer:
Given the information in the attached image;
The number of blue marbles is 5.
The total number of marbles is 10.
So, the probability of drawing blue as the first marble is;
![P_1=\frac{5}{10}=\frac{1}{2}](https://tex.z-dn.net/?f=P_1%3D%5Cfrac%7B5%7D%7B10%7D%3D%5Cfrac%7B1%7D%7B2%7D)
Also, since there is a replacement, the probability of drawing blue as the second marble is;
![P_2=\frac{5}{10}=\frac{1}{2}](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7B5%7D%7B10%7D%3D%5Cfrac%7B1%7D%7B2%7D)
the probability of drawing two blue marbles will be;
![\begin{gathered} P=P_1\times P_2 \\ P=\frac{1}{2}\times\frac{1}{2} \\ P=\frac{1}{4} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20P%3DP_1%5Ctimes%20P_2%20%5C%5C%20P%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%5Cfrac%7B1%7D%7B2%7D%20%5C%5C%20P%3D%5Cfrac%7B1%7D%7B4%7D%20%5Cend%7Bgathered%7D)
Therefore, the probability of drawing two blue marbles is;
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Hello!
I believe it's like this.. 2x+3=15. That number would be 6.
Hope this helps! ☺♥
