Which solution has the greater concentration?
WITCHER [35]

The higher concentrated solution is 0.250 mole LiCl dissolved in 250 ml of solution

( B).0.250mole of LiCl diluted in 250ml solution

<u>Explanation:</u>

<u>Procedure to find the intensity of the solution:</u>

To find the intensity of the solution, we have to use the following formula

M1V1=M2V2

250mL of a 0.500 M aqueous solution of LiCl is diluted with water

M1V1=(250) \times (0.500)=125M

250 ml of a 0.250M aqueous solution of LiCl is diluted with water

M2V2=(250) \times (0.250)=62.5M

Thus the PH level of a solution increases from ascending order, Therefore the Solution with 62.5M is a higher concentration than that of the solution with 125M.

1. Name two organisms that are competing for energy and explain HOW they compete.​
lutik1710 [3]

Answer:

There could be a few answers for this question, but my answer would be two different plants. Maybe a bush on the ground fighting for the energy of the sun with a tall tree. Leaves collect the energy from the sun and convert it to energy usable for the plant. a bush on the ground would be fighting for the sunlight with a tall tree.

Which law relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions? Boyle's law Charles'
Triss [41]
<span>The correct answer is ideal gas law.

when the ideal gas law formula is:

 PV = nRT ,

when P is the pressure. 

V is the volume. 

and R is the ideal gas constant.

T is the temperature. 

and n is the number of moles.

So, this is the law which relates pressure, temperature, volume and number of moles . and this law state that 1 mole of an ideal gas will occupy a volume V = 22.4 L</span>
