Answer:

1. 8.8kJ/mol

2. The process is not favorable.

3. The reason is in the answer.

4. Process 1.

Explanation:

1. ΔG° = ΔG° products - ΔG° reactants

ΔG° = -228.4kJ/mol - (-237.2kJ/mol) = 8.8kJ/mol

2. The process is not favorable because ΔG > 0

3. As the reaction is an equilibrium, a little amount of water will change from liquid to gas. This is the reason because of water has a measurable equilibrium vapor pressure.

4. Entropy is greater in process 1 because the structure of H2O(s) is more organized than H2O(l) (S of H2O(s) is lower than H2O(l)).

ΔS of H2O(s)⇄H2O(g) is greater than H2O(l)⇄H2O(g)

Explanation:cell division occurs to produce new cells from preexisting ones. the new cells are called daughter cells.the old cells are called parent cells.cell division may be mitosis or meiosis. Mitosis occurs in a somatic cell and produce four daughter cell. Meiosis occurs in sex cells and produce two daughter cells. Cell division usually involves Prophase, metaphase, anaphase and telophase.

Cell division occurs to ensure the continous existence of life.

Mitosis involve producing daughter cells with the same number of chromosomes as the parent cells while meiosis involves producing daughter cells with Half number of chromosomes.
