Answer: Option B) is the correct answer.

Explanation:

A polymer is defined as a molecule which has 'n' number of monomer units.

For example, (CH_{2}=CH_{2})_{n} is a poly ethene polymer.

Similarly, proteins are also polymers as they are made up of amino acids and contain number of repeated units just like polymers.

Thus, we can conclude that protein is made of polymers.

Answer:

The correct answer is B).

Explanation:

The factors that accelerate a chemical reaction are:

- Temperature: at a higher temperature, the speed of a reaction is increased.

- Pressure: the higher this is, the greater the collisions between molecules and an acceleration of the reaction speed will occur.

-Catalysts: correspond to substances that accelerate chemical reactions, an example are enzymes. There are catalysts that increase the reaction rate and others that generate the opposite effect (they are inhibitors).

There are also other factors that accelerate a chemical reaction such as the concentration of reagents.

If you have 40 grams of potassium nitrate in 100 grams of water at 20 C:
anygoal [31]

Answer:

Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.
