hanol, C2H5OH, is being promoted as a clean fuel and is used as an additive in many gasoline mixtures. Calculate the ?H°rxn for the combustion of ethanol.(?H°f [C2H5OH(l)] = -277.7 kJ/mol; ?H°f [CO2(g)] = -393.5 kJ/mol; ?H°f [H2O(g)] = -241.8 kJ/mol)
Initial temperature of rod = 100 °C; mass of H2O in calorimeter =130 g; cH2O = 4.184 °C g . (Assume the calorimeter has negligible heat capacity).
Write a net ionic equation for the reaction between aqueous solutions of ammonia and hydrofluoric acid.
Ethylene glycol, HOCH2CH2OH, is used as antifreeze. It is produced from ethylene oxide, C2H4O, by the following reaction. C2H4O(g) + H2O(l) ? HOCH2CH2OH(l)
Write and ionic equation to show what happens when we add small quantities of H+ ions to a buffer solution that contains equimolar amounts
It takes 49.0 J to raise the temperature of an 11.7 g piece of unknown metal from 13.0 C to 24.0 C. What is the specific heat for the metal?
what is the difference of the KBR specrtum in % transmittance and absorbance. and btw wavenumber and wavelength
The radioactive decay of radon follows first-order kinetics and has a half-life of 3.823 days. How many grams of radon will remain after 12.00 days if the sample initially had a mass of 455 g?
Since the air is going at 25 C and assuming atmospheric pressure, calculate the actual volume of air. Calculate the number of moles of CO2, H2O, O2 and N2 in the flue gas
One method used to store energy during times of low demand is by pumping water uphill into a reservoir. When energy demand exceeds the output produced by power plants
When determining the major contributor for a resonance structure, is it better to have a carbocation (positive charge on a carbon but without a complete octet) or is it better to have a positive charge on an electronegative atom like oxygen
