Which is the definition of adhesion?

1 answer:

4 0

A is incorrect. This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

B is correct. The property in which water molecules stick to one another tightly. The property in which water molecules easily evaporate into a gas.

C is incorrect. In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt

AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

What are the roles of a catalyst in the energetics of a chemical reaction?

7nadin3 [17]

Answer:

The correct answer is: catalysts lower the activation energy of the reaction.

Explanation:

Catalysts are substances that in our bodies are commonly represented by enzymes (specialized proteins) and that are used in chemical reactions to speed them up.

In order to achieve this, catalysts lower the activation energy of chemical reactions, which is a value of energy that must be obtained for the reaction to actually happen.

Catalysts are constantly used in our bodies and are responsible for the proper functioning of every organ. These catalysts can be used over and over again because they are not consumed in the reaction.
