Answer:
D
Step-by-step explanation:
You know that angles A are congruent. So , you just look to see what the angles are congruent to each other, and since D is in the second place as X, your answer would be D
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>
Hello :
the sum is arithmetic secquence of common -diff is :
(-7)-(-5) =(-5)-(-3) = (-3)-(-1) =-2 = d
the first term is : a1 = -1
<span>the formula of the sum : S= (n/2)(a1 +an)
n is number of term an = a1+(n-1)d</span>
Answer:
B
Step-by-step explanation:
According to the given situation,
If X, then Y indicates y depends on X
If Y, then Z indicates Z depends on Y
As per the given situation, Y is true also Z will be true on the other hand there no solution about x b as y depends on X
Therefore as per the above explanation, the correct answer is B and hence the same is to be considered
B. By solving for x, you get x=8.39,x=-2.39.
