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.

Explanation:
Hello, in this case, one could consider the undergoing chemical reaction as:
Thus, since 1.0 g of strontium carbonate is placed, the equilibrium equation takes the following form, excluding the solid-stated species and considering just the carbon dioxide as it is gaseous:
Hence, since at the beginning there is no carbon dioxide, its pressure at equilibrium equals Kp:
Which was clearly defined above.
Best regards.
The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.
Fraction = (1)
Here, initial pressure = 1.0 atm
final pressure =
First, convert torr into atm
1 atm = 760 torr
final pressure =
=
Now, put the value of initial and final pressure in formula (1)
Fraction =
=
Thus, fraction of the gas phase molecules =
