What is the name of this hydrocarbon

1 answer:

7 0

You haven't shown the structural formula but it's either an Alkene(double bond c=b between 2 carbons) or an alkane
If there is 1 carbon it is methane (methene is not possible as a carbon cannot double bond with itself)
If there are 2 carbons it could be ethane or ethene
If there are 3 carbons it could be propane or propene
If there are 4 carbons it could be butane or butene
If there are 5 carbons it could be pentane or pentene
Etc.

E.g ethane E.g. Ethene
H H H H

H---C---C---H C = C

Calculate the vapor pressure at 25 ?c of hexane above the solution. the vapor pressure of pure hexane at 25 ?c is 151 torr.

Studentka2010 [4]

One of the many ways in order to solve for the vapor pressure of pure components at a given temperature is through the Antoine's equation which is written below,
P = 10^(A - B/C+T)
where A, B, and C are constants and T is the temperature in °C and P is the vapor pressure in mm Hg.
For hexane,
A = 7.01
B = 1246.33
C = 232.988

Substituting the known values,
P = 10^(7.01 - 1246.33/232.988+25)
<em> P = 151.199 mm Hg</em>

Metallic sodium reacts vigorously with liquid bromine in the following reaction:

Luden [163]

First we look at the chemical reaction:

2 Na + Br₂ → 2 NaBr

number of moles = mass / molecular weight

mass = number of moles × molecular weight

number of moles of Na = 1000 / 23 = 43.48 moles

number of moles of Br₂ = 3000 / 160 = 18.75 moles

from the reaction:

if 2 moles of Na are reacting with 1 mole of Br₂

then X moles of Na are reacting with 18.75 moles of Br₂

X = (18.75 × 2) / 1 = 37.5 moles of Na

The limiting reactant is bromine Br₂.

After the reaction is complete you remain with Na as excess reagent.

moles of Na = 43.48 - 37.5 = 5.98 moles

mass of Na = 5.98 × 23 = 137.54 g

if reacting 1 mole of Br₂ produces 2 moles of NaBr

then reacting 18.75 moles of Br₂ produces Y moles of NaBr

Y = (18.75 × 2) / 1 = 37.5 moles of NaBr

mass of NaBr = 37.5 × 103 = 3862.5 g

a car traveling at a speed of 30.0 m/s encounters an emergency and comes to a complete stop. how much time will it take for the

ivanzaharov [21]

It will take 7.5 s for the car to stop.

One of the acceleration formulas is

$v_{f} = v_{i}$ +at, where

$v_{f}$ is the final velocity,
$v_{i}$ is the initial velocity,
a is the acceleration, and
t is the time.

0 = 30.0 m·s⁻¹ + (-4.0 m·s⁻²)t

4.0 s⁻¹ t = 30.0

t = $\frac{30.0}{ 4.0 \text s^{-1}}$ = 7.5 s
