Methanol (CH3OH) has been suggested as a fuel to replace gasoline. Write a balanced equation for the combustion of methanol, find ΔH °rxn, and determine the mass of carbon dioxide emitted per kJ of heat produced. Use the information from the previous exercise to calculate the same quantity for octane, C8H18. How does methanol compare to octane with respect toglobal warming?

I just need help with the last part of the problem. Thank you!   A sample containing 1200.0 grams of ice at -13.8°C is given 580.0 kJ of heat. ΔHfusion = 6.01 kJ/molΔHvap = 40.8 kJ/molSpecific heat of ice = 1.877 J/gKSpecific heat of water = 4.184 J/gKSpecific heat of steam = 2.013 J/gK. How much energy (in kJ) is needed to heat the 1200.0 grams of ice up to 0.00°C?  31.1 kJ How much energy (in kJ) is needed to melt 1200.0 grams of ice at 0.00°C to water at 0°C?  401 kJ How much energy (in kJ) is needed to heat the 1200.0 grams of water from 0.00°C to the boiling point of water?  502 kJ If you start at -13.8°C, what is the final temperature of the system after you have added the 580.0 kJ of heat? ? °C

For 1, locate the absolute humidity and the web-bulb temperature.

Molecular bromine is 24 percent dissociated at 1600 K and 1.00 bar in the equilibrium Br₂(g) ⇒ 2Br(g). Calculate (a) Kp, (b) A,Gº, (c) K₂ at 2000 K given that A₁HⓇ = +112 kJ mol-¹ over the temperature range.
