Answer:

D . A substance with a pH of 8

Explanation:

pH stands for <em>"Potential for Hydrogen." </em>This is an indicator of a solution's acidity or alkalinity. It is also used to tell <em>which chemicals are great for cleaning. </em>

pH 7 and pH 8 are both considered<em> "neutral pH,"</em> thus, solutions with these pH are often used as<em> dishwashing detergents </em>because they do not destroy the surfaces of objects. However, pH 8 is said to be<u> more alkaline in nature</u>. This allows it to destroy the residues, such as <em>fats and oils</em>, in pots and pans. It is the<em> pH of baking soda.</em>

how much hydrogen will be released during the interaction of potassium weighing 8 grams with hydrochloric acid
krek1111 [17]

Answer:

With an understanding of the ideal gas laws, it is now possible to apply these principles to chemical stoichiometry problems. For example, zinc metal and hydrochloric acid (hydrogen chloride dissolved in water) react to form zinc (II) chloride and hydrogen gas according to the equation shown below:

2 HCl (aq) + Zn (s) → ZnCl2 (aq) + H2 (g)

When preparing the diazonium salt, the solution is tested with potassium iodide-starch paper. a positive test is the immediate f
Dahasolnce [82]
KI-starch paper allows the detection of strong oxidizers such as nitrite. It is used here to control diazotization of 4-nitroaniline. Nitrite oxidizes potassium iodide in order to form elemental iodine which reacts with starch to a blue-violet complex. With KI-starch paper, enough sodium nitrite is added to produce nitrous acid, which <span>then will react with 4-nitroaniline to form a diazonium salt.</span>

Determine whether the disruption of the bonds or attractions occurs during protein hydrolysis or protein denaturation.
Aleonysh [2.5K]

Answer:

The disruption of the bonds or attractions occurs during protein hydrolysis which results in the loss for the primacy structure. The peptide bonds is the bond affected in this scenario.

The disruption of the bonds however only exist in the process of denaturation and this results in a change in the confirmation which could be secondary, tertiary, and quaternary structural related. And example of the bonds affected include salt bridges, disulfide bridges, hydrogen bonds etc.
