in the following conditions calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while the other remains at 275K
Suppose that a fully charged lead-acid battery contains 1.50L of 5.00M H2SO4. What will be the concentration of H2SO4 in the battery after 2.30A of current is drawn from the battery for 9.50 hours? Express the molar concentration numerically
what is the energy difference between the heats of formation you calculated for carbocation A and B?
