In stars helium atoms are used with hydrogen atoms in order to produce energy.
Answer: A )
After subtracting the volume needed from the volume dispensed, we got a remainder of 35ml
<h3>Subtraction of Numbers</h3>
Given Data
- Volume of Hexane dispensed = 40ml
Let us compute the amount of excess hexane/ the volume that will remain
Remainder = The difference in volume dispensed and the volume needed
Remainder = 40-5
Remainder = 35 ml
The remainder is 35ml

The Number of moles required for MTBE is 2 as per molarity based chemistry theories.
- A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
- Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
- It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
- In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
- Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
- It is miscible in water and less dense than water. Boosts the octane of gasoline.
- Therefore it has 2 moles of oxygen.
