Answer:
(a) 
(b) 
(c) 
Explanation:
Hello,
(a) In this case, since entropy remains unchanged, the constant
should be computed for air as an ideal gas by:


Next, we compute the final temperature:

Thus, the work is computed by:

(b) In this case, since
is given, we compute the final temperature as well:

And the isentropic work:

(c) Finally, for isothermal, final temperature is not required as it could be computed as:

Regards.
Answer:
Choice A: approximately
.
Explanation:
Note that the unit of concentration,
, typically refers to moles per liter (that is:
.)
On the other hand, the volume of the two solutions in this question are apparently given in
, which is the same as
(that is:
.) Convert the unit of volume to liters:
.
.
Calculate the number of moles of
formula units in that
of the
solution:
.
Note that
(sulfuric acid) is a diprotic acid. When one mole of
completely dissolves in water, two moles of
ions will be released.
On the other hand,
(sodium hydroxide) is a monoprotic base. When one mole of
formula units completely dissolve in water, only one mole of
ions will be released.
ions and
ions neutralize each other at a one-to-one ratio. Therefore, when one mole of the diprotic acid
dissolves in water completely, it will take two moles of
to neutralize that two moles of
produced. On the other hand, two moles formula units of the monoprotic base
will be required to produce that two moles of
. Therefore,
and
formula units would neutralize each other at a two-to-one ratio.
.
.
Previous calculations show that
of
was produced. Calculate the number of moles of
formula units required to neutralize that
.
Calculate the concentration of a
solution that contains exactly
of
formula units:
.
The flow rate of a liquid substance using any type of method is determined through the use of a type of measurement. It's often measured using velocity, an area or through the means of elapsed time. It's also called as continuity.
The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the carboxylic group.
<h3>What is the Grignard reagent?</h3>
The Grignard reagent is a compound that contains alkyl magnesium halide.
a) The student will be unsuccessful to prepare a Grignard reagent from 4-bromocyclohexanol because of the -OH group that reacts with the Grignard reagent when formed.
b) The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the carboxylic group.
c) The compound (2S, 3R)- 2,3-Dibromobutane has a specific rotation, [a]D, 0⁰ because it is a meso compound.
d) This is because, the tertiary alkyl halide is more prone to elimination reaction giving the alkene.
e) This is because, the reaction may be occurring by an SN1 mechanism and the rate determining step is the formation of the carbocation.
