which is a stronger base in water? Ch3O-, or Ch3COO-?
A) CH3O-, because the negative charge is localized on the oxygen making the species less stable and therefore a better proton acceptor.
B) CH3O-, because the negative charge Is de-localized on the oxygen, making the species more stable and therefore less likely to accept a proton.
C) CH3COO-, because the negative charge is de-localized over the two oxygens, making the species more stable and therefore less likely to accept a proton.
D) Ch3COO-, because the negative charge is loaded on one of the two oxygens, making the species less table and therefore a better proton acceptor.

Which is the stronger base in water, NH2- or -OH? a) NH2-, because the negative charge is delocalized making the nitrogen more willing to accept a proton. b) NH2-, because the nitrogen is less electronegative and cant hold the negative charge as well as oxygen c) -OH, because the negative charge is delocalize making the oxygen more willing to accept a proton. d) -OH, because oxygen is less electronegative and cant hold the negative charge as well as nitrogen. e)...
Pre-Lab Exercise 2-3 Chemical Bonding One of the more challenging concepts to grasp in chemistry is chemical bonding, a topic that pops up again and again in A&P: We revisit it in cytology, the nervous system, blood, respiration, and digestion-to name just a few First let's do some basics. Use your textbook and this unit to answer the following questions 1. Do metals donate or accept electrons? What do they become after they donate/accept electrons? 2. Do nonmetals donate or...
Two Biology problems Please answer all of these with details otherwise please 'do not answer any' A. The figure above shows two types of carbohydrates commonly found in plants. Which of the following is a correct statement about these carbohydrates? a. A is an energy storage polysaccharide because its beta-glycosidic linkages are more resistant to hydrolysis. b. B is a structural polysaccharide because its beta-glycosidic linkages are more easily hydrolyzed. c. B is an energy storage polysaccharide because its alpha-glycosidic...
Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
A covalent bond is a bond in which electrons are shared between atoms of elements. A covalent bond can be polar or nonpolar. In a nonpolar covalent bond, the bond is between two identical atoms and the electrons are evenly shared between the atoms.In contrast, in a polar covalent bond, the bond is between two nonidentical atoms and the electrons are unevenly shared between the atoms. The uneven sharing of electrons takes place because of the difference in the electronegativity...
What are the instruments that have been utilized for the review article discussions? ` 1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

i need help with the prelab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
