Consider the following exothermic reaction at equilibrium: CO(g) + H2O(g) H2(g) + CO2(g). What happens to the system when carbon dioxide is added to the mixture?
Draw all of the eclipsed and staggered conformations for the c3-c4 bond in hexane starting with the conformation that has the lowest energy.
Which of the following is false? A. Molecules with strong intermolecular forces have higher surface tension. B. Molecules with strong intermolecular forces have higher viscosities.
To the right of this flask is another flask containing Ne at 1.00 L and .450atm The last flask on the right holds Ar at 2.00 L and 25.0 kPa. Explain what is partial pressure of each gas and the total pressure when all of the connections are opened
Explain what is the final temperature of the beverage as well as spoon system? Presume no energy is lost from the system. Presume hot chocolate has the same heat capacity of water 4.18 J/gK as well as a density of 1.08 g/mL and the spoon has a hea..
A container with a removable partition contains gas A and gas B. Gas A is at 400K and 10.0 atm and gas B is at 400K and 4.00 atm. The partition is removed and the gases mix.
Calculate the concentration of NaOH if 25. ml of the solution is needed to neutralize 18.9 ml of .237 M HCl
A 1.630 g sample of naphthalene, C10H8(s), is completely burned in a bomb calorimeter assembly and a temperature increase of 8.44°C is noted.
Using the given information, write the complete thermochemical equation for this reaction. Explain how you developed this equation, and specify what the equation tells us about the reaction?
As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample? Assume that the temperature was held constant.
Initially A sample of a substance of 23.43 g weight has temperature 24.2 °C then it absorbs heat and reached to temperature 122.0 degree Celsius; calculate the specific heat of this substance if it absorbs 2167 joule heat
Need some assistance: 2a) Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.170 M in KCN. For HCN, Ka = 4.9 x 10^-10 (pka = 9.31). Use the equilibirum approach to calculate this pH
