5. Some undiluted acids are more corrosive when diluted
wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

You disrupt all hydrogen bonds in a protein. what level of structure will be preserved?
Alex777 [14]
I believe the primary structure will be preserved. The secondary level of proteins is defined by patterns of hydrogen bonds between the main chain peptide groups. Therefore distorting the Hydrogen bonds disrupts the secondary structures. The primary structure on the other hand is not affected by disruption of the hydrogen bond since these structures refers to the sequences of amino acids in the polypeptide chains that are joined by the peptide bonds.

SVETLANKA909090 [29]

Answer:

it reflects green light and absorbs other colors.

Explanation:

The term pigment derives from the Latin pigmentum, which means the <em>substance that produces color</em>.

Pigments provide color to cells and tissues.

In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.

Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.

The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.

The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.
