Explanation & Answer

I think only registered student of that university can access this as I'm not able to access it.You can sent it here directly the assignment.
Hi,I'm able to access your account.I've one request: It'll be really great if you could review the last 2 assignments so I can receive my compensation for the same.
Hi,Please find attached solution document.

does it make difference if it is handwritten?If not, then go ahead and submit it.
Okay😀
Sure, I'll.
Hi,How can I respond to your peer's responses for the discussion?I'll complete the work for your individual and you'll handle the peer;s related work as I've no idea how to access that stuff + how they are gonna give you grade.so I'll submit only the answer of "Prompt:Hypothesize a way that you could force a reaction to reach 100%. Explain why it would work and why the reverse reaction wouldn’t occur. "by tonight.
oh!then I'll share typed answer for your work.and I believe it work like if we give good responses to others then they'll also gave to good response (may be!)Can you do the peer's review work?
Hi,Please find attached word document for answer of Week-2 Discussion.

Hypothesize a way that you could force a reaction to reach 100%.
Explain why it would work and why the reverse reaction wouldn’t
occur:
A reaction in dynamic equilibrium can get close to completion depending on its
equilibrium constant, which is a ratio between products and reactants at a certain
temperature. The chemical reaction is not reaching to their 100% completion point
because their equilibrium point/ product is more stable than reaction’s end product
so it will not fully complete.
So, in general, end product forms but simultaneously it has tendency to form
equilibrium product. So, in Hypothesizing this, we have to go with a reaction where
the possibility of converting end product to equilibrium product is vanished.
Let us proceed with a reaction
X(aq)+Y(aq)



Z(aq) + W(g)

X, Y and Z are in aqueous solution but W being a gas.
The reaction is carried out in open vessel so that gaseous product(W) can
escape and reaction can’t happen in reverse direction.
(If it is in an open vessel then once Z and W’s concentration start increasing,
they will start forming X and Y, reaction in reverse direction starts and it will
never reach 100 %completion

In this case, the forward reaction is forced to reach 100 %.
Instead Gaseous product(W), if W be volatile product, then also this reaction will
reach 100% completion. As X and Y are reacting and forming Z and W, volatile liquid
product(W) start vanishing due to distillation. That’s how this reaction is forced to
reach 100%.

Post-Lab Questions

Determine whether the amount of reaction products you observed agrees with stoichiometric
predictions. One underlying assumption is that the baking soda is the only limiting reactant. In other
words, there is essentially an unlimited supply of acetic acid in the vinegar bottle, and the reaction
output is only dictated by the amount of baking soda you add – every mole added results is a mole of
carbon dioxide pro...
