Write a chemical equation to show (a) the main reaction in this experiment, (b) why Vanillin is more soluble in aq. NaOH than plain water, (c) why adding aq. HCI precipitates the product. (d) What would happen if we tried to carry out the reduction in aq. HCl instead of aq. NaOH? 1. 2. How many moles of hydride can be transferred from each mole of NaBHa? 3. Of the reagents used today, which one is both corrosive and flammable?...
What is the purpose of performing the dark reaction for this experiment? Briefly explain why it is important to include the dark reaction in the PSII activity assay Experiment is Photosystem II Activity Assay and Measurement of Chlorophyll
Determination of the Rate Law for the Iodination of Acetone in
Acidic Solution
I conducted an experiment to determine initial concentrations of
reactants, reaction times, and reaction orders for the iodination
of acetone.... here is my data followed by some questions... help
please??
1. How do you double the concentration of one of the reactant
solutions in each experiment? What reagent should you use to
control the total volume of each experiment?
2. Could you reduce the concentration of a...
1. Briefly explain why the heat capacity of the calorimeter must be calculated in this experiment. The experiment includes the calibration of the calorimeter, the measurement of temperatures to determine enthalpy change. Chemicals include ammonium hydroxide, hydrochloric acid and ammonium chloride.
Briefly explain the central argument in Judith Jarvis Thomson's essay "A Defense of Abortion." What position does she grant 'for argument's sake'? What does she claim concerning rights in general, rights for women, and rights for fetuses? What is her general assertion concerning the morality of abortion? Do you agree with her position/conclusion? Do you agree somewhat? Or do you strongly disagree? In answering, engage directly with Thomson's essay (i.e., pick out a specific claim and explain why you think...
techniques. 2. Briefly explain each of the following. (1) Why are all of the solutions used in this experiment 1.0 x 10-M in HNO3? (2) What are the hazards of using solutions that are 1.0 x 10 M in HNO3?
Below is the mechanism for a by-product of a lab experiment. In that experiment, we were attempting to produce 1-bromobutane from butanol, but we could produce 2-bromobutane. I would like for you to explain to me in terms of structure: why do we see the formation of this particular carbocation in the first step of the addition of HBr to the double bond (third step for the overall reaction below)? Next, rationalize your structural explanation using molecular thermodynamics. i.e. Explain...
1)-Briefly explain the role of the hydrochloric acid during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine freebase and hydronium chloride to help your discussion and circle the organic species that is more soluble in water. 2)- Briefly explain the role of the potassium hydroxide during the liquid-liquid extraction procedure. Draw the acid-base reaction between lidocaine hydrochloride and potassium hydroxide to help your discussion and circle the organic species that is would be more soluble in the organic...
Why do you think communication is vital to the success of every business organization? Explain briefly in three paragraphs
Post lab questions 1.Why are inoculated plates incubated in the inverted position? 2.What term is used to describe the type of culture on the Petri plate you made? 3. Do you think that the growth on your plate represents all the different microbes that were living in the environment you took them from? .Why did you swab one plate with a sterile swab? Dont just say it acted as a control. What specifically was it supposed to show in this...
