The molecule is as follows;
H₃C---C==CH₂
|
H
--- represents single bonds whilst == represents double bonds
Single bonds are formed by sigma orbital head on overlap between sigma orbitals of C and H in the case of C-H bonds and between C sigma orbitals in the case of C-C bonds
the number of sigma bonds are therefore the number of single bonds which are:
6 C-H bonds
2 C-C bonds
altogether 8 sigma bonds
p orbitals side- on overlap forms a pi bond. In double bonds, there's one sigma bond and one pi bond.
number of double bonds - 1 C=C therefore one pi bond
Answer is <span>4) 8 sigma and 1 pi</span>
There are 20 boys in the class. The ratio is 4:3 so that means 4 out of 7 are boys and 3 out of 7 are girls. Divide 35 by 7 and you get 5. 5 times 4 is 20. 5 times 3 is 15. add them together and you have 35 students in total. So 20 students are boys and 15 students are girls.
Answer:
Step-by-step explanation:
Given
<em>See attachment</em>
<em></em>
Required
Determine the total surface area, T
T is calculated using:
Substitute values for r and h
Remove bracket
Take 
So, we have:
--- approximated.
<em>Hence, the surface area is 1300 square inch</em>
Answer:
Hey there!
I=PRT
I=3200(0.035)(1)
I=112
The interest is 112 dollars.
Hope this helps :)
Hi ok make a diagram that goes horzontaly and make 9 lines to get 10 squares then make another diagram that is equal to the other one and draw one lune in the middle shade in 7/10 on the first one then shade in 1/2 in the second one
