Use enthalpies of formation to calculate the standard enthalpy of reaction for the following methane-generating reaction of the methanogenic bacteria:
4 H2(g) + CO2(g) ----> CH4(g) + 2 H2O(g)
Given the three formation equations and their enthalpy values, calculate the enthalpy of the given reaction.
Assuming that the tank is a sphere having an inner diameter of 0.52 m, estimate the amount of nitrogen vaporized per day for an insulation thickness of 2.5 cm and an ambient temperature of 21 degrees celsius. Assume that the outer temperature of t..
The surroundings are at 285 K. The gas may be assumed to be ideal. Calculate the entropy change for the system, the surroundings, and the universe when the gas increases in volume by a factor of four in each of the following processes
The value that should be reported for the number of moles of gas calculated from the ideal gas equation given the following data (R = 0.08206 L•atm/mol•K, P = 76.00 cmHg, V = 1.000 L, and t = 1°C) is
A shipment of protein bars has arrived from Orkasia. These bars are labeled as containing 100% of the daily protein requirement for an average woman, which is 65 g of protein/day.
Do the same for halogenation of an alkene -- as review. Now we do not have HBr as a product. Explain why not -- in terms of balancing the reaction, especially from the standpoint of H atoms.
100 mL of 0.150 M acid H2A are mixed with 100 mL of 0.1600 M NaOH. Calculate the [H+] of the resulting solution at equilibrium. Ka1 = 1.0 x 10^-5 Ka2 = 1.0 x 10^-7
What is the reaction order with respect to \rm A. Can the same method be used to find reaction order of B and C
How much ice in grams would have to melt to lower the temperature of 51.0 g of water from 65.0*C to 0*C
A refrigeration tank holding 5.00 L of Freon gas (C2Cl2F4) at 25°C and 3.00 atm pressure developed a leak. When the leak was discovered and repaired, the tank had lost 76.0 g of the gas.
how much heat must be added to 36.2g sample of iron to increase its temperature by 250.0 degree C.
