Answer:

The freezing point will decrease.

Explanation:

Whenever a solute is added to a solution/solvent, it leads to the <u>depression in the freezing point</u> of that solution/solvent. Depression in freezing point of a solution on addition of a solute is a colligative property. A colligative property is a physical property which depends upon the number of solute added not on the nature of solute that means it does not matter whether we are adding 1000 particles of sugar or salt in water, the depression in freezing point will occur by the same °C. Also, the more a solute is added the more will be the depression in freezing point.

The formula for depression in freezing point is mentioned as under:

               Δ T = K x m

where,    Δ T = freezing point depression;

                  K = cryoscopic constant;

                  m = molality of solution.

For example: The freezing point of water is 0 °C but as soon as we add a 92 gm solute like NaCl (common salt) in 1000 gm of water,  it's freezing point will lower to −3.72 °C.

Which of the following is NOT a benefit of fertilizer?
just olya [345]

Answer:

Allows farmers to grow plants using very little soil

Explanation:

Fertilizer helps us to return the nutrients to the soil for new or current plants to grow. These nutrients were spent by the plants that were there or the soil was not that rich with nutrients, to begin with. It will not replace soil and growing plants without soil is called hydroponics. Fertilizer is very useful in agriculture currently and most likely will continue to be a good way to grow plants for a while.

What type of reactions creates bonds between monomers? What type of bond breaks bonds between monomers?
Tcecarenko [31]

Answer: dehydration synthesis reactions and hydrolysis.

Explanation:  

<em>Large biological molecules often assemble via dehydration synthesis reactions, in which one monomer forms a covalent bond to another monomer, releasing a water molecule in the process. </em>

<em />

<em>The process of splitting the bond between monomers is called hydrolysis.  Since a water molecule was lost during dehydration synthesis, hydrolysis brings the water back.</em>

What rule or reasoning did you use to decide how to label the cut end of the short piece of magnet?
andrew-mc [135]

Answer:

<em>You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will <u>become the new north or south poles of the smaller pieces.</u></em>
