he solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane i

s permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same.

If we examine after 3 days, there will be a decrease in the concentration of NaCl and a decrease in the water level.  

<u>Explanation:</u>

  • If we inspect the following 3 days, there'll be a reduction inside the convergence of NaCl and a lessening inside the water level. This focus is diminished in 2 different ways, by expanding the solute or diminishing the water.
  • Expanding the solute will build the arrangement's focus. This should be possible by just including a greater amount of your compound into the arrangement and dissolving it. It may not help in case you're utilizing a watery arrangement that is as of now disintegrated in water.

You can utilize a procedure called dialysis to diminish the water in an solution.

  • Spot your answer in a dialysis pack that is shaped of semipermeable substance. Presently place the pack in an answer which has a high grouping of a particle. Accordingly, water will be kept concealed separately from the pack through the semi-penetrable film by hurrying out of the sack to the arrangement.

Determine the net iconic equation for the following chemical reaction: HCl(aq) + NH4OH(aq)———-&gt; NH4Cl(aq) + H2O(I) Hint: HCl(
katen-ka-za [31]

Answer : The net ionic equation will be,

H^{+}(aq)+OH^{-}(aq)\rightarrow H_2O(l)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

HCl(aq)+NH_4OH(aq)\rightarrow NH_4Cl(aq)+H_2O(l)

The ionic equation in separated aqueous solution will be,

H^+(aq)+Cl^-(aq)+NH_4^+(aq)+OH^-(aq)\rightarrow H_2O(l)+NH_4^+(aq)+Cl^-(aq)

In this equation, NH_4^+\text{ and }Cl^- are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

H^{+}(aq)+OH^{-}(aq)\rightarrow H_2O(l)

A fruit and oatmeal bar contains 142 nutritional calories. Convert this energy to calories
Alekssandra [29.7K]
Answer is: a<span> fruit and oatmeal bar contains 142000 calories.
</span>A nutritional calorie<span>, or kilocalorie, is equal to 1000 calories.
</span>E = 142 kcal · 1000 cal/kcal.
E = 142 000 cal.
Calorie (cal)<span>, or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.
</span><span>One small calorie is approximately 4.2 joules.
</span>A calorie is a unit of energy.

HI(aq)+NaOH(aq)→ <br> what the final balanced chemical equation with the phases included
julia-pushkina [17]

Answer:

HI(aq)+NaOH(aq)\rightarrow NaI(aq)+H_2O(l)

Explanation:

Hello there!

In this case, for this neutralization reaction, it is possible to realize that one the neutralization products is water (pH=7) and the other one is the salt coming up from the cation of the NaOH and the anion of the HI:

HI(aq)+NaOH(aq)\rightarrow NaI+H_2O

Moreover, since the solubility of NaI is large in water, we infer it remains aqueous whereas the water is maintained as liquid:

HI(aq)+NaOH(aq)\rightarrow NaI(aq)+H_2O(l)

Which is also balanced as the number of atoms of all the elements is the same at both sides.

Best regards!
