What is hypotonic,isotonic and hypertonic solution?

Chemistry
1 answer:
Andrew [12]4 years ago
3 0
An isotonic environment is when the concentration of solutes and solvent (water) are the same. 

<span>When a cell is hypertonic, it shrinks because the concentration of solvent/solutes are unequal. If the inside of the cell has less solutes and more solvent, the solvent inside (water) will diffuse out the cell because of the concept of "going doing the concentration gradient". Anything will travel from a high concentration to a low concentration. In the case of hypertonic, water will move out the cell and causes it to shrink. </span>

<span>Hypotonic is when the cell is enlarged by water moving inside. So a hypotonic cell will look like it's big and expanded. Water goes where there is less concentration of it. You can also think about it from another perspective. Water always go where there is more solutes. So if the solute concentration like sodium or sugar or ect. is greater inside a cell or a piece of potato, then water will go there (since if there is a high concentration of solutes, then there is low concentration of solvent). </span>

Which substance can be broken down by chemical means
Maru [420]

Answer:

1. Ammonia  

Step-by-step explanation:

Ammonia, NH₃, is a <em>compound</em> of nitrogen and hydrogen.

Thus, it can be broken down by chemical means into the <em>elements</em> nitrogen and hydrogen.

The other options are <em>wrong</em>, because Al, Sb, and Pb are elements. They cannot be broken down chemically into simpler substances.

How many grams of Carbon are in sample of 400 grams of Co2?​
RoseWind [281]

Answer:

Mass of carbon = 109.1 g

Explanation:

Given data:

Mass of carbondioxide = 400 g

Mass of carbon = ?

Solution:

Molar mass of carbon = 12 g/mol

Molar mass of CO₂ = 44 g/mol

Mass of carbon in 400g of  CO₂:

Mass of carbon = 12 g/mol/44 g/mol × 400 g

Mass of carbon = 109.1 g

The ΔG° of the hydrolysis reaction of ATP is –7.3 kcal/mole, but in a cell the actual ΔG is much more negative. What is the reas
yanalaym [24]

Answer:

ΔG° is for ideal (fixed) or standard conditions which cannot be found at the cellular level while ΔG is dependent on the quantities of reactants and products present at a specific time

Explanation:

ΔG° is fixed value for a given reaction that indicates the direction in which the reaction will proceed in a chemical equation under ideal conditions and because conditions within a cell varies and are unlike standard conditions, ΔG° cannot predict the direction of a cellular reaction at any given time. To predict the direction of progression of a reaction within the cell, ΔG is used, which depends on the amounts of the reactants and products present at a particular time

A student finds two unlabeled flasks of clear liquids. One is believed to be 0.1 m nacl and the other to be 0.1 m naclo3. What i
KonstantinChe [14]

Answer:

  • Add AgNO₃ solution to both unlabeled flasks: based on solubility rules, you can predict that when you add AgNO₃ to the NaCl solution, you will obtain AgCl precipitate, while no precipitate will be formed from the NaClO₃ solution.

Explanation:

<u>1. Adding AgNO₃ to NaCl solution:</u>

  • AgNO₃ (aq) + NaCl (aq) → AgCl (s) + NaNO₃ (aq)

<u>2. Adding AgNO₃ to NaClO₃ solution</u>

  • AgNO₃ (aq) + NaClO₃ (aq) → AgClO₃ (aq) + NaNO₃ (aq)

<u />

<u>3. Relevant solubility rules for the problem.</u>

  • Although most salts containing Cl⁻ are soluble, AgCl is a remarkable exception and is insoluble.

  • All chlorates are soluble, so AgClO₃ is soluble.

  • Salts containing nitrate ion (NO₃⁻) are generally soluble and NaNO₃ is not an exception to this rule. In fact, NaNO₃ is very well known to be soluble.

Hence, when you add AgNO₃ to the NaCl solution the AgCl formed will precipitate, and when you add the same salt (AgNO₃) to the AgClO₃ solution both formed salts AgClO₃ and NaNO₃ are soluble.

Then, the precipiate will permit to conclude which flask contains AgCl.
