Answer :
(a) The number of moles of D produced can be, 6.67 moles.
(b) The volume of D prepared can be, 24.5 L
Explanation :
The given chemical reaction is:
Part (a) :
From the balanced chemical reaction, we conclude that:
As, 3 moles of A react to give 5 moles of D
So, 4 moles of A react to give 
moles of D
Thus, the number of moles of D produced can be, 6.67 moles.
Part (b) :
As we know that 1 moles of substance occupies 22.4 L volume of gas.
As, 
volume of B gives 
volume of D
As, 9.8 L volume of B gives 
volume of D
Thus, the volume of D prepared can be, 24.5 L
The products being more stable than the reactants is the factor which would reduce the yield of a reaction and is denoted as option B under standard conditions.
<h3>What is a Chemical reaction?</h3>
This is the process in which one or more substances which are referred to as reactants are converted into new substances which we call the products.
A chemical reaction involves atoms exhibiting different bond formation so as to ensure they acquire an octet configuration and promotes proper stability of the products.
When the products are more stable than the reactants it means it is unable to form other products thereby decreasing the yield which is why it was chosen as the most appropriate choice.

Marine west coast, humid subtropical, and Mediterranean.
You can use any form of the Ideal Gas Law, but usually one form is more convenient, depending on the information given.
There are three forms of the Ideal Gas Law.
Form 1
P
V
=
n
R
T
If the question gives you the number of moles then
, this is the most convenient one to use.
Form 2
P
V
=
m
M
R
T
, where m is the mass of the gas and
M is its molar mass.
If the question gives you the mass
m
, this is the most convenient one to use.
Form 3
P =
ρ
M
R
T
, where ρ is the density of the gas.
If the question gives you the density
ρ
, this is the most convenient one to use.
Answer:
By ensuring she is giving speed endurance training
Explanation:
Speed endurance training would be the most ideal in helping an athlete to maintain and even increase her competitive potential.
The speed endurance training would help the athlete maintain and attain a high speed for a longer duration of time.
This would make the athlete get used to running an improved time for much longer distances.
