The answer is C. Phospholipids because Lipids mean "Fat"
A sample 0. 100 moles of a gas is collected at at STP . 2.24 is the volume of the gas in liters.
The STP means standard temperature and pressure.
At STP,
Temperature = 0 °C =273 K
Pressure = 1 atm
We get value of volume by using ideal gas equation,
PV = nRT
- P is the pressure of the gas = 1 atm
- V is the volume occupied by the gas = ?
- n is the number of the moles = 1 mole
- T is the temperature of the gas = 273 K or 0 °C
- R universal gas constant = 8.31 J/ mole × K
Calculation,
Since, one mole of a gas occupy 22.4 L volume at STP
So, for 0.1 mole volume occupy = 22.4L × 0.1 mole/1 mole = 2.24L

Oxygen(O)
Explanation:
Oxygen is the most reactive of all the listed elements. One can determine their reactivities based on the electronegativity values.
- Every element combines with one another to attain stability like the noble gases.
- Electronegativity is the relative ease with which the atoms of elements attracts valence electrons in a chemical bond.
- On the pauling's electronegativities table of elements, carbon is 2.5, oxygen 3.5 and Cl is 3.0
- Oxygen will have the highest reactivity and the most tendency to combine with other atoms.
