When you use a starch solution instead of a protein solution, the water will move from the dialysis tube to the solution. This is because water moves from where it is in a higher concentration to an area <span>where it is in a lower concentration

Match the theoretical motions of particles with their associated phases. Solid, Gas, Liquid. 1. oscillation about a fixed point
viktelen [127]
The correct combination of <span>theoretical motions of particles with their associated phases is given below:

1) Solid : </span>oscillation about a fixed point . Because solids do vibrate (atoms/molecules of a solid oscillate around their mean positions)<span>
2) Gas : </span>translation, vibration, rotation. The gas molecules are free to rotate, oscillate & vibrate. <span>
3) Liquid: </span>rotation and vibration. The liquid molecules are free to rotate & vibrate.

A more clear pictures (at atomic & molecular level is shown below):

4. Consider the following reaction:
Lyrx [107]

Answer:

High temperatures

Explanation:

NaHCO₃ (8) + HCH,O₂ (aq) → H₂O (l) + CO₂ (g) + NaC,H₃O₂ (aq)

As the flask gets cooler to the touch as the reaction proceeds, the reaction is endothermic. This means that ΔH is positive (ΔH>0).

As a gas is formed (bubbles are formed), ΔS is positive (ΔS>0).

<em>In terms of ΔG:</em>

  • ΔG = ΔH - TΔS

<em>In order for the reaction to be thermodynamically favorable, ΔH has to be negative</em>, thus:

  • The reaction is favorable if TΔS > ΔH.

The greater the temperature, the easier it would be for TΔS to be greater than ΔH.
