Starch and cellulose are both produced by plants, yet one is easily digested by animals and the other is not. Discuss the differences in the structures of these two molecules and how this may impact whether they can be digested.

Answer:

Option 2

In process I & II entropy of the system increases proceed from left to right.

Explanation:

Entropy is an extensive property of the system. It means it depends on the amount or quantity of the system

In case for process 1

since one mole sodium chloride dissolve in water and it dissociate into two ions i.e. Na⁺ and Cl⁻

For process 2

CaCO₃(s) → CaO(s) + CO₂(g)

Change in gaseous moles = (Product moles - reactant moles)

                                 ⇒ Δng = 1

Since  Δng > 0 it means randomness increases of the system from left to right. So, ΔS > 0

Final answer:

Processes I (dissolving NaCl) and II (decomposition of CaCO3) show an increase in entropy, whereas process III (freezing water) shows a decrease. Therefore, the entropy of the system increases for processes I and II, not III.

Explanation:

The student has asked which processes have an increasing entropy as they proceed from left to right. Entropy is a measure of the disorder or randomness in a system, and changes in entropy can be predicted based on phases changes, the dispersion of matter, and the change in the number of particles in a system.

For the process of dissolving NaCl (s) into Na+(aq) and Cl-(aq), entropy increases due to the dispersion of the solid into ions, hence increasing the randomness of the system. Therefore, process I has an increasing entropy. In process II, we have CaCO3 (s) decomposing into CaO (s) and CO2 (g), leading to an increase in the number of gaseous molecules, which significantly increases entropy compared to the original solid state. Lastly, process III involves the transition of H2O (l) into H2O (s), which means that water is going from a more disordered liquid state to a more ordered solid state, decreasing the entropy of the system.

Considering these details, the entropy increases for processes I and II but decreases for process III. Therefore, the correct answer to the student's question is option 2, which indicates that entropy increases for processes I and II.

The mixing of solute in the solvent is called solubility. In a solution, there are two types of components, these components are solute and solvent.

• Solute - a component that presents in less amount.
• Solvent - a component that is present in a large amount.

According to the question, the torr is defined as the torr is a unit of pressure based on an absolute scale, defined as exactly 1/760 of a standard atmosphere.

The equation is  

hence,

After solving the equation,

Hence, the solubility is 0.093.

Answer: The correct option is (a).

Explanation:

If two gases are present in a container, the total pressure in the container is equal to the sum of the all the individual pressures exerted by the individual gases in a container.

Individual pressure exerted by the individual gas in a container is called partial pressure of that individual gas.

So, total pressure of gas in container is:

Where = Total pressure exerted by the gases in the container.

= Partial pressure of gas 'a'

= partial pressure of gas 'b'

The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.

So, A
