What is the difference between hypertonic and hypotonic

Chemistry
1 answer:
Bess [88]3 years ago
5 0
Answer: A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane. If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume.

Picture:
Meaning of hypertonic: (1): having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. (2) of or in a state of abnormally high muscle tone.

A cell has the reaction Co2+ (aq) + Cd(s) -------> Cd2+ (aq) + Co(s) E0cell = +0.120 V What is Ecell when [Co2+] = 0.00100 M
musickatia [10]

Answer:

USe this Nernst equation and find your required answer

Explanation:

E = E0 -  [0.0592 /n ] log [Cd+2]/[Co2+]

Wher Eo is  +0.120 V

[Cd+2] =0.1

[Co2+] = 0.001

n is number of electons transfered int he process and in your case it is = 2

E= 0.120- 0.0296 * log 100

  = ........  V

Which of the following statements is true about both nuclear fusion and nuclear fission? They occur in the sun. Heavy atoms are
galina1969 [7]
<h2>Answer </h2>

Some mass changes into energy

<u>Explanation </u>

Some mass changes into energy are true about both nuclear fusion and nuclear fission. These both reactions produce large amounts of energy. Nuclear fusion is the process in which two light nuclei combine to form a larger nucleus. On the other hand, nuclear fission is reverse in which a heavy nucleus breaks into two light nuclei. Nuclear decay and transmission are also types of nuclear reactions. The matter is not destroyed in nuclear reactions.

How many mL of a stock 50% (w/v) KNO3 solution are needed to prepare 250 mL of a 20% (w/v) KNO3 solution?
Andre45 [30]

Answer:

100ml of a stock 50% KNO3 solutions are needed to prepare 250ml of a 20% KNO3 solution.

Explanation:

In the given question it is mentioned that

     S1=50%

      V2=250ml

      S2= 20%

We all know that

                     V1S1=V2S2

                     ∴V1=  V2×S2÷S1

                     ∴V1=  V2S2×1/S1

                      ∴V1= 250×20÷50

                       ∴V1= 100ml
