Answer:
Element Y, or the third option
Explanation:
Alkanes are insoluble in water, but soluble in ether. Their boiling points are pretty low, barely reaching 200 degrees, so element Y is an alkane.
Equation:
C2H2 + O2 -> CO2 + H2O
Balanced using given coefficients: 2, 3, 4, 5
*Remember: these numbers can be used more than once (as stated in the question)
2 C2H2 + 5 O2 -> 4 CO2 + 2 H2O
