PLEASE HELP! Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold wa
Sergio039 [100]

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

A plant cell is placed in distilled water, as shown in the figure. There is a net uptake of water by osmosis, causing the cell t
Korvikt [17]

Answer:

The water potentials (Ψ) of the cell and its surroundings are the same.

Explanation:

When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.

When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.

Which do the following is an impact of growing the same crop on a farm for several years?
Taya2010 [7]
<h3>Hi!</h3>

The correct answer is D. Decrease in soil fertility.

<h3>Explanation:</h3>

A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.

<h3>Hope this helps!</h3>
