The Background section of this lab explains why weight percent (%w/w) can beuseful for comparing the relative amount of a desired or "active" compound indifferent products.During the lab, a major goal will be to decide which of your experiment flasks yielddata that would allow you to correctly calculate the %w/w of sodium bicarbonate inthese tablets.Let's assume that you correctly choose one flask for this calculation. If the amount ofNaHCO3 in that flask was 2.70 g and the original weight of the tablet was 4.60 g,what is the %w/w NaHCO3 in the tablet that went into this flask? GIVE YOURANSWER TO TWO DECIMAL PLACES.Your Answer:Answer

What mass of oxygen gas is consumed by the reaction of 2.66 g of ethanol? Round your answer to 3 significant digits. 0%
Why do you multipy the # of H2S mols by 4, when 4 corresponds to the reactory amount of O2?The logic there is somewhat confusing to me.I understand how/why you found out the mols of the equation but dividing the sample's MM by the equation confuses me.
Propose an alternative method for purifying the product today. Briefly describe how you would determine was effective. the reactionis attached and the procdeudre is below Synthesis of Dibenzalacetone (A) In this lab you will need to determine the amounts of the reactants you will use. We will use 0.0125 moles of acetone. You need to: (1) convert this into a volume in mL, (2) Calculate the number of moles of benzaldehyde needed based on the balanced chemical reaction, (3) Convert the number of moles of benzaldehyde into volume in mL. Your reagent table should reflect your calculated values. Mix the benzaldehyde and acetone based on the volumes from your prelab calculations in a testtube. Add 25 mL of 10% NaOH solution to a 125 mL Erlenmeyer flask along with a stir bar and 20 mL of ethanol. Make sure the temperature of the solution in the flask is below 25 C before proceeding. Add half of the solution from your test tube to the flask. Allow the solution to stir for 15 minutes…

Note: This is an algorithm question so each attempt will have unique set of measurements. The following results were obtained when a sample of white cranberry juice was analyzed to determine its Vitamin C content. A 82.0 mL sample of the juice was placed in a flask with excess H2SO4, excess KI, and 11.00 mL of 0.07 000 M KIO3. Titration with thiosulfate solution required the use of 1.63 mL of 0.08826 M. Calculate the concentration of Vitamin C in the juice sample as mg Vit C per 100 mL juice. Here are some steps to help you work your way along the problem. All the reactions in the Background apply. • How many total millimoles of I are produced from the Reaction 4 between KI and KIO3? • How many millimoles of I are consumed in Reaction 3 with thiosulfate? . Using your previous two answers, how many millimoles of I reacted with the Vitamin C in the juice? • How many milligrams of Vitamin C were in the juice sample? • What is the concentration of Vitamin C in the juice sample expressed as…
I want to prepare a working formulae for manufacturing 250 ml hand washing liquid (hand wash), for this can you make a master formulae for this? Please mention all the ingredients along with the required percentage or amount. And also mention all the step by step procedures for making this hand washing liquid. Please answer at your own easy words. I will rate you positive if you do so.

Consider the following scenario: After the first compound elutes off of the column, you collect multiple fractions without seeing the next compound begin to elute. What change might you want to make before you continue taking fractions?
Can you calculate the limiting reagent, theoretical yield and% Reaction Yield shown using reaction stoichiometry? The calculations given in the benzalacetone synthesis experiment were the volume of 3mL of benzaldehyde, 1mL of acetone and the mass of dibenzalacetone 2.69g. With this data I calculated the other data shown in the table. Thank you! Psd.Where it says " Que deseas hacer?" in the photo that is the Benzaldehyde data.
pls help will rate u thank you!
