Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions (1 atm and 25 °C) Use enthalpy of formation data to calculate the number of moles of CO2 (g) produced per megajoule of heat released from the combustion of each fuel under standard condition (1atm and 25 degrees celcius) a)Coal , C (s, graphite) b) Natural gas, CH4(g) c) Propane, C3H8 (g) d) Octane, C8H18 (l) ( delta Hf= -250.1 kJ . mol ^-1 All these answers have to be in mol.MJ^-1
benzene ring with a 2 carbonyl joined by an O in the middle and a iso propal group is on the other carbonyl. (would be a symmetric anhydride if it weren't for the benzene and isop-ropral substituents on the two carbonyls)
a solution is prepared by adding 50.0ml of 0.050m HBr to 150.0ml of 0.10m HI .calculate the concentrations of all species in this solution HBr and HI are both considered strong aicds ?
Performing the elimination with potassium tert-butyl alcohol. At what temperature will the reaction mixture begin refluxing?
12.0 moles of gas are in a 7.00L tank at 25 degrees Celsius. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a= 2.300L^2 and b=.0430mol.
A solution of H2SO4(aq) with a molal concentration of 4.37 m has a density of 1.233 g/mL. What is the molar concentration of this solution?
A foul-smelling gas produced by the reaction of with was collected, and a 1.00 sample was found to have a mass of 1.52 at STP. What would be the formula.
Also, at the end 1.31 g of 4,4-dimethyl-2-cyclohexen-1-one was obtained. My question how to calculate percent yield for 4,4-dimethyl-2-cyclohexen-1-one and theoretical yield for this lab.
In the formation of dibenzalacetone, do you expect the configuration of the double bonds in this compound to be E,Z, or a mixture of both? WHY?
170mL of O2 gas is collected over water at 25 degrees C and the total pressure is 742 mm Hg. The vapor pressure of water is 23.8 mm Hg at this temperature. What would the volume of the dry gas be at STP? ( hint Daltons Law and Combination Law are ..
