Ethane (molar mass 30.07 g/mol) boils at-88.6℃ Methanol has almost the same molar mass (32.04 g mol), but boils at 65℃, which of the following BEST explains the reason for the large discrepancy in boiling point? Choose one: A. Ethane is ionic and, therefore, has a lower boiling point. B. Methanol is ionic and, therefore, has a higher boiling point. C. Both compounds only exhibit van der Waals forces. D. Both compounds are polar. Methanol is more polar than Ethane....
Enter your answer in the provided box. A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature rose by 4.46°C. If the heat capacity of the bomb plus water was 9.20 kJ /°C, calculate the molar heat of combustion of methanol. kJ/mol
Enter your answer in the provided box. A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature rose by 5.14°C. If the heat capacity of the bomb plus water was 9.41 kJ / °C, calculate the molar heat of combustion of methanol. kJ/mol

Methanol (CH3OH) can be synthesized according to the reaction below: CO(g) + 2 H2(g) --> CH3OH(g) What volume (in liters) of H2 gas at a temperature of 400 K and pressure of 720 mmHg is needed to synthesize 45 g of methanol? some information you may find useful: C = 12.01 g/mol H= 1.01 g/mol O = 16.00 g/mol give your answer to one decimal place
Methanol (CH3OH) burns according to the equation 2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(l), ΔH°rxn = –1454 kJ/mol. A) How much heat, in kilojoules, is given off when 150.0 g of methanol is burned? [ Select ] B) How many grams of CO2 are produced when the amount of heat determined in part A is released? [ Select ] Molar masses: CH3OH = 32.04 g/mol O2 = 32.00 g/mol CO2 = 44.01 g/mol H2O = 18.02 g/mol
The vapor pressure of methanol (32.043 g/mol), CH3OH, is 94 torr at 20 °C. The vapor pressure of ethanol (46.07 g/mol), C2H5OH, is 44 torr at the same temperature. Calculate the total vapor pressure above a solution of 32.4 g of methanol and 23.9 g of ethanol.
