Explain the process of balancing a chemical equation and why is this necessary? I understand that new substance uses the same atoms from the original, it just moves places and attaches to different atoms (the same atoms from the reactants) but I'm still a little confused on the concept.
You identified your unknown compound. How you could use this compound to determine the Kf value for ethyl alcohol? Explain what you would do experimentally.
Problem- SiCl4 is exposed to radiation (photons) with a wavelength of 3 x 10-7m. Determine if the compound is stable under these conditions or not. Solve this problem by making use of Pauling's treatment of polar covalency
A solution contains 0.400 mol of calcium nitrate as well as 6.500 mol of water. Compute the vapor pressure of the solution at 55 degrees Celsius. The vapor pressure of pure water at 55 degrees Celsius is 118.1torr. Presume that the solute complete..
Determine the mole fractions and partial pressures of CO2, CH4, and He in a sample of gas that contains 1.25 mole of CO2, 1.59 moles of CH4, and 3.41 moles of He, and in which the total pressure is 5.78 atm.
In the decomposition of hydrogen peroxide, the percentage yield of oxygen is 93%. What is the actual yield in grams of oxygen if you start with 100 grams of H2O2.
