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.

Lady bird [3.3K]

Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Mitochondrial DNA can be traced for generations. It is because of the fact that unlike nuclear DNA, mitochondrial DNA rarely gets mutated. The frequency of mutations in the mitochondrial DNA is approximately one every 3,500 years per nucleotide. That is why mitochondrial DNA of a person is almost similar to his/her direct maternal ancestor. So, it can be used to match lineages amongst people.

How much more CO2 is in the atmosphere today compared to 150 years ago?

ludmilkaskok [199]

Answer:

Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But humans have burned so much fuel that there is about 30% more carbon dioxide in the air today than there was about 150 years ago, and Earth is becoming a warmer place.
