Know what makes a solution acidic or basic (the pH number and the ions).
Brrunno [24]

To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.

In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.

  • In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content.  According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
  • In basic solutions, the concentration of OH- ions is higher than that of H3O + ions.  If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution.  Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.

What makes essential fatty acids amino acids different from ones that arent essential?
Svetlanka [38]

Answer:

\rB. nutrients that are essential cannot be made by the body, so they must be obtained from food.

Explanation:

If we look at the definition of essential fatty acids, it clearly states that these are fats which human body cannot prepare but are essential for proper functioning of body. Since body cannot synthesize them on their own, therefore we must obtain them through a diet rich in them. Two main essential fatty acids are:

  • Alpha-linolenic acid (omega-3)
  • linoleic acid (omega-6)

They play essential functions in body sucg as :

Production of hormones

Better adrenal and thyroid activity

Regulation of inflammatory and immune responses, function and development of brain.

Supporting the development of healthy skin and hair.

Option B is the best option.

Hope it helps!

Thank you

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms
Delvig [45]
<h3><u>Answer;</u></h3>

A. <em>18 hydrogen atoms </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
  • <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
  • Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.

Find out what do the terms algal bloom and red tides signify​
ch4aika [34]

Answer:

Find out what do the terms 'algal bloom' and 'red-tides' signify. Algal bloom refers to an increase in the population of algae or blue-green algae in water due to an enrichment of nutrients, resulting in discoloration of the water body. ... Red tides are caused by red dinoflagellates (Gonyaulax) that multiply rapidly.

I hope it's helpful!
