Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. ... The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.
Explanation:
The elements involved here are non-metals. The bond that forms between non-metals is a covalent bond where each atom shares one or more electron with the other so that both become stable. The number of shared electrons has to be equal for both.
Now, hydrogen needs only one electron to fill its outermost level and be stable and the same goes for fluorine, therefore, each of them shares one electron with the other.
Based on this, the answer would be:
<span>Hydrogen and fluorine share one electron with each other.</span>
The mass of gas in the tank has been 222 g. Thus, option B is correct.
The volume occupied by 1 mole of gas at standard temperature and pressure has been 22.4 L.
<h3>Computation for the Mass of gas</h3>
The volume of gas in the tank has been given as 170 L.
The moles of gas in the tank has been:
The moles of gas in the tank has been 7.58 mol.
The molar mass of the gas has been 32.0 g/mol.
The mass of gas has been calculated as:
Thus, the mass of gas in the tank has been 222 g. Thus, option B is correct.
