Calculate the amounts of C 7 H 8 , C 7 H 16 , and H 2 in the output stream express your answer (in mol s -1 ).
A mixture of CO, CO2 and O2 is contained within a 275 mL ?ask at 0 ? C. If the total pressure is 780 torr, the CO has a partial pressure of 330 torr and the CO2 has a partial pressure of 330 torr, what is the partial pressure of O2
Determine the percent yield for this reaction as N2(g) + 3 H2(g) ? 2 NH3(g)
A sample of methane gas (CH4) at 18.8 oC is heated. The pressure increases from 1.78 atm to 2.46 atm, and the volume of the sample changes from 4.09 L to 1.89 L.
Consider the cell described below: Al| Al3+ (1.00 M) || Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.60 mol/L.
A 1.30 g sample of dry ice is added to a 760 mL flask containing nitrogen gas at a temperature of 25.0 degrees Celcius and a pressure of 735 mmHg. The dry ice is allowed to sublime.
The number of moles in 15.39 g of C2H6O (molar mass =46.1 g/mol) is ,You transfer a sample of gas at 17 degrees C from a volume of 4.71 L and 1.10 atm to a container at 37 degrees C.
Determine how long will it take for the concentration to decrease to 0.13 mol/L express your answer in seconds.
Greg Nard added an equivalent of 3,4-epoxy-4-methylcyclohexanol to an ether solution of methyl magnesium bromide and then added dilute hydrochloric acid.
The constant pressure molar heat capacities of ice and water are 37.7 J/ mol K and 75.3 J/ mol K respectively. The molar enthalpy of fusion of ice is 6.01 kJ/ mol at 0.00° C. The system consists of a 105 gram sample of H2O, initially in the form o..
