Calculate the work done in joules whne 2.5 mol of H2O vaporizes at a constant pressure of 1.0 atm and at a temperature of 25 degrees c. Assume the volume of liquid H2O is negligible compared to that of vapor. Given 1 L atm = 101.3
Carbon Dioxide and water form during combustion of methane. How many grams of water vapor form when 2.39 g of methane react completely with excess oxygen? CH4 (g) + 2 O2 (g) ------> CO2 (g) + 2 H2O (g)
This compound, C5H10, gives a negative test for C-C double bonds and gives only one monobromo substitution product, C5H9Br. Propose a structure for this compound
the temperature decreases by 0.2010 K. Calculate the molar heat of solution of KCN.
If it takes 52 J of energy to warm 7.40g of water by 17°C, how much energy would be needed to warm 7.40g of water by 55 °C
The concentration of carbon in a carbon-metal alloy is found to be 4.73x10^1 kg/m3. It is also known that the concentration of carbon in wt% in the alloy is 1.318x10^0 .
The answer to Kinetics, The symmetry factor Beta was determined to be 0.4 for an activation controlled Ag deposition process. At overpotential n = -0.400 V the current density was found to be j = -5.125 A/dm^2.
if 4.00 grams of water at an initial temperature of 1.00 degrees c absorbs 33.00 joules of heat by how many degrees c

Why does the electron energy threshold of dissociation almost always exceeds the actual dissociation energy in contrast to dissociation, stimulated by vibrational excitation
If you have 340.0 mL of water at 25.00 °C and add 120.0 mL of water at 95.00 °C, what is the final temperature of the mixture. Use 1.00 g/mL as the density of water.
How long will it take in minutes until 42% of the original NO2 remains if the rate constant is 0.0066L/(mol sec) and the initial amount of NO2 is 0.45 mol/L?
One way the rate law for a reaction can be experimentally determined is to monitor the concentration of each reactant continuously over the span of the reaction. Explain in no more than one paragraph how a rate law is derived from the data obtaine..
