Chapter 7, Problem 7.67CP
For the unbalanced combustion reaction shown, 1 mol of ethanol. C2H5OH, releases 327 kcal (1370 kJ):
- (a) Write a balanced equation for the combustion reaction.
- (b) What is the sign of ΔH for this reaction?
- (c) How much heat (in kilocalories) is released from the combustion of 5.00 g of ethanol?
