Answer:
Given, 0.29 g of hydrocarbon produces 448ml of CO2 at STP. then, C2H5 is the emperical formula of hydrocarbon . n = 2 , hence, molecular formula will be C4H10
A as the lower temperature in Celsius corresponds to a lower Kelvin temperature thus reducing movement
This is the Lewis Dot structure for oxygen
