The thermochemical equation for the burning of ethyl alcohol is C2H5OH(l) + 3O2(g) --> 2CO2(g) + 3H2O(l) ?H = -1,367 kJ What is the enthalpy change (in kJ) for burning 9.68 g of ethyl alcohol
calculate the amount of heat in joules (q) required to affect this temperature change and the total change in internal energy, ?U. Note that some books use ?E as the symbol for internal energy instead of ?U.
For the reaction SO2(g) + NO2(g) = SO3(g) + NO(g), the equilibrium constant is 18.0 at 1,200 degrees C. If 0.050 M mole of SO2 and 0.10 M moles of NO2 are placed container, what concentration os SO3 will be present at equilibrium?
Determine the mass of 100 mL of solution for this reaction: the results were 2.05 g of NaOH, 102.05 grams (total solution-when added with the water).
An unknown compound contains only C, H, and O. Combustion of 4.40 g of this compound produced 8.79 g of CO2 and 3.60 g of H2O. What is the empirical formula of the unknown compound. CHO
A sample in a 1.0 mm cell absorbs 75.0% of the incident light at 510 nm. If the solution is 0.075 M, its molar absorptivity (M-1 cm-1) is:
