How much energy is required to turn 9 g ice at 249 K into steam at 426 K?
Specific heat of ice = 2.077 J/g·KSpecific heat of water = 4.180 J/g·KSpecific heat of steam = 2.042 J/g·KH2O heat of fusion = 6.00 kJ/molH2O heat of vaporization = 40.6 kJ/mol
The atomic mass of Potassium 39 is 38.96371 AMU. Calculate the binding energy for a mass of this nuclide using 1.008665 AMU for the mass of the neutron, 1.007276 AMU for the mass of the proton, 0.00054858 AMU for the mass of the electron
Commercial concentrated nitric acid is 69.0 % by mass HNO3 and has a density of 1.42 g/mL. Calculate the molarity of concentrated nitric acid.
Analyze the groups bonded to the carbon of interest. Every H contributes +1, and every oxygen contributes -2. An -OH group contributes (-2 + 1 = -1). Ignore carbons bonded to the carbon of interest. The sum of the oxidation states must be zero, si..
