please help with this question.
Extra credit Homework on Acid-Base Titration You can use the technique of titration to determine the concentration of a mixture of sodium carbonate and sodium bicarbonate. Titration is performed using a solution with a known concentration of hydrochloric acid (HCI). During the titration, HCl reduces gradually the alkalinity of the solution until the pH is acid. The reaction occurs in two stages in the first part you titrate the total amount of carbonates present in...

Extraction of solids: Experiment outlined below
Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.
Preliminary separation obtain a sample (1.0g) of the mixture. weigh the sample and record it. this sample should consist of a 2:1:1 mixture (by mass)...
can you double check the structures drawn in the boxes
please.
The structures from the other page will be used in Question 4
and 5

At the bottom of the page are two different chemical reactions
in structural form. How would you write the equations in chemical
form? I am writing a lab report and I am trying to figure out how
to determine the chemical formula of these two so that they can be
written on my report on microsoft word.

Draw the reactant(s) or product(s) that would be involved in the following chemical reactions. You do not have to balance the equations. [T12] Ethanol reacts with butanoic acid in the presence of H2SO4 to produce an ester. Butan-2-ol can undergo an elimination reaction in the presence of sulfuric acid.
Hi! Please try to answer as much as you can from the questions below. I would greatly appreciate it! question 1) How would you separate a mixture of m-toluic acid and 3’-aminoacetophenone using extraction technique? question 2) In the separation described in #5, what needs to be done to isolate crystals of m-toluic acid? Write all chemical reactions associated with this separation and isolation procedure. question 3) An organic compound A has the following solubilities at room temperature: 12 g...
