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
What is the freezing point of a solution of ethylene glycol (antifreeze), a nonelectrolyte, that contains 140. g of C2H6O2 dissolved in 290. g of water? Use molar masses with at least as many significant figures as the data given.
The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant
In the IUPAC naming system, all alkanes end in the suffix ane and begin with a prefix determined by the number of carbon atoms in the molecule
How many grams of aluminum oxide are produced when 50.3g aluminum react, When 0.510 mole aluminum is reacted in a closed container with 7.90g oxygen, how many grams of aluminum oxide can form?
Picric acid is a monoprotic acid that has been used in the leather industry and in etching copper. However, its' laboratory use has been restricted because it dehydrates on standing and can become shock sensitive
What is the percent-yield of H2 In the reaction below when an equimolar mixture of CH4 and CO2 with an initial total pressure of 20.0 atm reaches equilibrium at 1200. K, at which Kp = 3.548 x 106
Build and elucidate a prototype model, Use your model to recommend a schedule of the burning and, if necessary buying, fuels, Use your model and its results to offer.
For the decomposition of sodium bromide: NaBr = Na(s) + 1/2Br2(liquid) the change in Gibbs Free Energy (delta G) is 349 KiloJoules What is the free energy of formation of NaBr(solid)?
Write a balanced net ionic equation for the reaction of KMnO4 with the saturated solution of CdC2O4 in diluted H2SO4. The major products are Mn2+ and CO1
Imidazole, acting as a nucleophile, catalyzes the hydrolysis of phenyl acetate by attach on the carbonyl carbon atom of the ester. The imidazole displaces the phenoxide anion and forms acetyl imidazole
