Amides can be hydrolyzed to yield carboxylic acids. The conditions are much more severe than those for other carboxylic acid derivatives. Acidic hydrolysis occurs by addition of water to the protonated carbonyl, followed by proton transfer to make the nitrogen a better leaving group. The reactions are reversible, and the reaction is driven to completion by protonation of NH3 at the end. Draw curved arrows to show the movement of electrons in this step of the mechanism.

What type of organic molecule comprises the majority of a potato?

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table?

Why is it important for scientists to review and repeat the work of other scientists? 1.a scientific theory must be tested three times before it is proven. 2.the scientific method only applies to repeated experiments. 3.an experiment may have had errors that the scientists didn't recognize. 4.the results of individual scientists may be influenced by bias. 5.an experiment must be performed twice before the data can be analyzed.
