In chemistry, there is a class of compounds called alkanes. They have the general formula 2x+2, where stands for a carbon
atom and H stands for a hydrogen atom. The subscript x stands for the number of carbon atoms, and the subscript 2x + 2 stands for
the number of hydrogen atoms in one molecule of the compound,
Carbon atoms Hydrogen atoms Alkane Formula
Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have?
a. 18 atoms
c. 10 atoms
b. 16 atoms
12 atoms

Alkanes: CnH2n+2

n=8 --> C8H18. So it is 18 atoms

Step-by-step explanation:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
