Determine the empirical formula of the hydrocarbon: (C and H only)
Find moles of C and H:
moles C = 0.55 mol C
moles H = 0.545 mol H
Get smallest ratio of C, H (divide by 0.545):
The empirical formula: CH
Balanced equation: 2CH + O2 → CO2 + H2O
A sample of a hydrocarbon is combusted completely in O2(g) to produce 24.01 g CO2(g), 4.917 g H2O(g), and 342 kJ of heat.
Do you think that the hydrocarbon is one of those listed in Appendix C? Explain your answer.
