It is a viscous outermost layer surrounding the cell wall. It is composed of either polysaccharides or polypeptides of both (~2%) and water (~98%). They are present only in some species of bacteria. The capsule is of 2 types; macro-capsule (capsule with a thickness of 0.2 μm or more...
In an experiment, ferric ions were reacted with thiocyanate. How might the results differ if ferrous ions were used instead? Explain the differences in conductivity of NaCl, CaCl_2, and AlCl_3. Describe chemical tests that could distinguish between acetic acid and acetaldehyde....
What ester is formed when the carboxylic acid is treated with ethanol (CH_3 CH_2 OH) in the presence of H_2SO_4? HCO_2H Which benzylic halide reacts faster in an S_N1 reaction? Explain. What is the mechanism for the basic hydrolysis of methyl benzoate? What is the best synthesis o...
The defining characteristic of a reducing sugar is thatit can mutarotate through the open chain form to produce an aldehyde. Monosaccharides are reducing compounds, but methylated derivatives are not because they become locked in acetal structure which does not allow them to mutarotate. Why sucrose ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
To address the question of the origin of LUCA, it is necessary to examine models for how the Earth formed, what geochemical environments may have been available on the early Earth, and what types of organics could have been produced in each. ...
Answer and Explanation:1 Ethanol has two carbon atoms bonded to each other, one of which is bonded to an alcohol group (-OH). The structure of ethanol is given below. Me... Learn more about this topic: Ethanol | History, Structure & Formula ...
a) Diethyl ether b) Ethanol c) Water d) Acetaldehyde What alcohol might the given alkene have been made from? Which of the following is a primary alcohol? A)CH3CH2OH B)(CH3)2CHOH C)(CH3)3COH D)(CH3)2CHCH(CH3)OH E)CH3OCH3 What is the bonding functional group for ethanol...
Explain each answer. a. The liquid level in the eudiometer tube is lower than that in the beaker, but this is not taken into consideration in the calculati Describe chemical tests that could distinguish between acetic acid and acetaldehyde. Why is Iodine (I_2) considered a good contrast...
Formaldehyde (Group 1), acrolein (Group 2A), acetaldehyde, and crotonaldehyde (Group 2B) have been identified in tobacco smoke and are classified by the IARC as carcinogens. The formation of these compounds is mainly due to tobacco combustion and pyrolysis, since these compounds are poorly ...
