Answer: C2H4
Explanation:
The percentage composition of ethanol ( C2H5OH ) consist of 52.2% Carbon, Hydrogen of 13.0 and 34.8% of Oxygen.
The percentage composition of ethane gas (C2H6) consist of 80.0% carbon and 20.0% hydrogen.
The composition of Ethylene Glycols i.e C2H4(OH)2 is Carbon of 39.7%, 9.7% hydrogen and 51.6% oxygen.
The percent composition of c2h4 is 86% carbon, and 14% hydrogen.
From the information given, the substance with the highest percentage of carbon is C2H4
A bulk property is also an intensive property, meaning that it is a physical property that does not depend on the size of the system. examples of bulk properties are color, density, melting/boiling point, pressure, and solubility.
Based on your lists, choice d contains all bulk properties: boiling point, surface tension, vapour pressure.
