C4H10 (g) + (6.5) O2 (g) --> 4CO2 (g) + 5H2O (g)
Smallest coefficient of C4H10 is 1.
First, balance out the Carbon and Hydrogen atoms as they are limiting.
Second, calculate the number of Oxygen atoms and minus away those found in C4H10.
Divide the number with 2 as oxygen exists as O2. [It is OK to put a fraction in front of the molecule as long as there is 1 atom used in the reaction. ]
Ethanol contains an alcohol group (-OH), which includes hydrogen bonding. Hydrogen bonding is stronger than other IMFs such as Van der Waals forces and Dipole-Dipole.
Ethene only has Van der Waals forces as it is an alkene with only C-H or C-C bonds. These means that the forces are not as strong.
Since ethanol contains hydrogen bonding, it will take a higher temperature in order to break these bonds, and thus results in a higher boiling point than ethene.
200 ml is 1/5 of a liter, so the answer is five times the number of moles present in the solution. 0.6 moles/0.2 liter = x moles/1.0 liter. Solving for x gives 0.2 x = 0.6 or x = 3.0 M
so the answer is c
