The combustion of ethane proceeds according to equation 2C2H6 + 7O2 → 4CO2 + 6H2O. The enthalpy change for combustion of 1 mol of this hydrocarbon equals –1600.0 kJ/mol. Use the following from Hess's law and calculate the enthalpy of formation of 1 mol of ethane, if ΔHf (CO2) = −393.5 kJ/mol, ΔHf (H2O) = −241.8 kJ/mol, ΔHf (O2) = 0.
Discuss selectivity mechanism and their utilisation of 1,3 dithion and lithium disopropylamide (LDA)
How do I calculate the Ksp, Delta G, and Delta S from my data table? The experiment aims to find the solubility curve of potassium nitrate dissolving in water. For example, when 2 grams of KNO3 dissolve in 5 ml of H20, crystals reappeared at 25° celsius.
How many grams of water can be made when 17.5 moles of HNO3 are consumed
Balance the reaction for the combustion of propane:
C3H8+?O2→?CO2+?H2O
If I start with .713 moles of hydrogen and excess bromine, how many moles of hydrogen bormide can I make?
Gas X has a molar mass of 100 g/mol and Gas Y has a molar
mass of 32 g/mol. How much faster or slower does Gas Y
effuse from a small opening than Gas X if they are at the same
temperature?
800.0 mL of Helium is at 55.0 \circ
∘C and 0.64 atm. What will the pressure be if the temperature changes to 100.0 \circ
∘C if the volume remains the same?
Examine the importance and impact of isomerism in industry
research case studies in order to consider the formation of different isomers during manufacture, how their presence may influence the industrial process, the differences in properties that they might have, and the possible consequences of ignoring the presence of isomerism.
In a Coulometric redox titration, we have 100 mL water with some KCl from salt bridge in one beaker, and 100 mL water with some KCl and 1 mL of 0.02 M CH3COOH in another beaker. 1.5 amps, 10 V, 500 sec until color change.
