I have an experiment that I have do to find the percent composition of an unknown mixture of sodium bicarbonate and sodium chloride. The materials that I have are the unknown mixture of sodium bicarbonate and sodium chloride, 1 M hydrochloric acid, 1 M sulfric acid, 1 M sodium hydrxide, pure sodium chloride and pure sodium carbon and i can use any other common laboratoy materials. I need the simplest experiment possible to figure out the percent compostion of the unknown mixture. I am just completely stuck and need some guidence to get me on the right track.

Using the data from the table, determine the percent
composition of the unknown mixture. (using stoichiometry)
How much Sodium Bicarbonate is in the
Mixture?
How much Sodium Chloride is in the
Mixture?
Using the percent compositions, determine the percent
error using the following information:
Actual % comp of Sodium Bicarbonate = 80%
Actual % comp of Sodium Chloride = 20%
Reactions: NaHCO3 (aq) + HCl (aq) + NaCl (aq) + CO2 (g) + H20 (1) Table 1 Trial Final Mass...
this is the data I have now

Please help! this is due in a matter in time! I dont know what
procedures to use! plz help me with ALL the planning questions!
Thank You so much your help is HIGHLY appreciated. And the
procedures have to some how correlate with the summary questions.
YOU DONT HAVE TO ANSWER THE SUMMARY QUESTIONS. Thank you so much
Kind soul.

I need to write out a procedure for extraction and recrystallization of a 1:1 (by mass) mixture of 1,4-dichlorobenzene/ethyl 4-aminobenzoate. So far, I have that I am starting with extraction using 1 g. of the mixture and dissolving it in about 15mL of diethyl ether. Then I am putting it in a separatory flask and adding 15mL of 1M HCl to get layers. To the organic layer, I will add sodium sulfate and put in rotovap to get a solid....
You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...
Solution Stoichiometry Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) a) What volume of 2.75 M HCl in liters is needed to react completely (with nothing left over) with 0.750 L of 0.300 M Na2CO3? b) A 565-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 10.1 g CO2. What was the concentration of the HCl solution? How do I...
all
of our classes are online now and i have no idea HOW to do this.
please explain with steps if you can. thank you!
