<u>Answer:</u> The number of moles of gas remaining in the lungs is 0.063 moles
<u>Explanation:</u>
The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.
The equation used to calculate number of moles is given by:
where,
are the initial volume and number of moles
are the final volume and number of moles
We are given:
Putting values in above equation, we get:
Hence, the number of moles of gas remaining in the lungs is 0.063 moles
Then it has lost 4 electrons meaning it is now positively charged
<span>The very first step you should do is to bromine water to each of them. Then you can recognize </span>the unsaturated compound, because as you know it will decolourize during adding bromine water, so we can make a conclusion that it will undergo as an addition reaction. Hope you will agree with me and fing this answer helpful for you. Regards!
