Explain what is the morality of NaOH if 41.67 ml solution is required to neutralize 0.2625 grams of pure H2C2O4*2H20
sketch a graph of potential energy versus dihedral angle about the c-c bond of 12-dichloroethane. show the energy
A compound with a formula C10H16 takes up one mole of H2 on catalytic hydrogenation. Give possible structures for it. If it takes up two moles of hydrogen on reduction, give one structure that fits this information.
Carbon-14 has a half-life of 5730 years. A sample of carbon with a mass of 0.120 g has an activity of 40 decays/hr. The initial specific activity is assumed to have been 900 decays/hr/gram.
A gas expands and does P-V work on the surroundings equal to 285 J. At the same time, it absorbs 216 J of heat from the surroundings. What is the change in energy of the system?
