Answer:

Rank the following chemical species from lowest absolute entropy (So) (1) to highest absolute entropy (5) at 298 K?

a. Al (s)

b. H2O (l)

c. HCN (g)

d. CH3COOH (l)

e. C2H6 (g)

Explanation:

Entropy is the measure of the degree of disorderness.

In solids, the entropy is very less compared to liquids and gases.

The entropy order is:

solids<liquids<gases

Among the given substances, water in liquid form has a strong intermolecular H-bond.

So, it has also less entropy.

Next acetic acid.

Between the gases, HCN, and ethane, ethane has more entropy due to very weak intermolecular interactions.

HCN has slight H-bonding in IT.

Hence, the entropy order is:

Al(s) < CH3COOH (l) <H2O(l) < HCN(g) < C2H6(g)

jeka94

Explanation:

Plants are autotrophic organisms which prepare their food with the help of photosynthesis. Plants can have both asexual or multi-sexual reproduction.

Amoeba is a single celled eukaryotic organism. It moves through pseudopodia and it does not have any definite shape. Amoeba can have only asexual reproduction.

The given functions for amoeba and plants are sorted as follows.

Functions of Amoeba:

  • has only offspring with identical genes and traits.
  • surrounds and engulfs food particles.
  • move freely in their environment.

Functions of Plants:

  • makes food from carbon dioxide,water, and sunlight.
  • can have offspring with different genes and traits.

Answer:

a. What makes this an oxidation-reduction reaction? (1 point)

Loss of electron by the aluminum and the gain of electron by the silver

b. Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction and which is the reduction reaction. (3 points)

oxidation half reaction: Al → Al3+ + 3e-

Reduction half reaction: Ag+ + e- → Ag

c. What is oxidized in the reaction? What is reduced? (2 points)

Aluminum is oxidized and silver is reduced

d. In this simple electrochemical cell, what functions as the anode? What is the cathode? (3 points)

In a simple electrochemical cell the electrode where oxidation takes place is the anode. And the electrode where reduction reaction happens is the cathode.

e. Is this a galvanic cell or electrolytic cell? Explain your answer. (2 points)

An electrolytic cell because the reaction converts electrical energy into chemical energy

Not sure about e and f!
