Problem- So, I know I'm just missing something simple here, but I am trying to balance the chemical equation in order to determine the concentration of [OH- ] in my saturated solution of Ca(OH)2-CaCl2. We titrated with HCl. Please help with determining the balanced equation! Ca(OH)2-CaCl2(aq) + HCl(aq) is just not making sense to me. Should reply all parts for five stars
A vitamin C containin sample was titrated to the blue colored endpoint with 19 ml of 0.12 M iodine solution. How many grams of Vitamin C were in the sample
Explain the heat of vaporization for the compound is 27.49 kJ/mol. Compute the heat required to convert 23.0 g ofC2Cl3F3 from a liquid at15.00°C to a gas at 82.00°C.
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Perutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin
Problem- Sort the smaller peptides according to whether they are- likely to form or if they will not form at all during this process.
