90. alkanes are a class of molecules that have the
general formula c h7+2, where n is an integer
(whole number). the table below gives the boil-
ing points for the first five alkanes with an odd
number of carbon atoms. using the table, con-
struct a graph with number of carbon atoms on
the x-axis.

a. what are the approximate boiling points for
the c2, c, cg, and cg alkanes?
b. which of these nine alkanes are gases at room
temperature (20°c)?
c. how many of these nine alkanes are liquids at
350 k?
d. what is the approximate increase in boiling
point per additional carbon atom in these
alkanes?

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
