chamistry
HI is a strong acid; i.e., it ionizes 100%; therefore, (H^+) = 0.006M pH = -log(H^+) Get pOH from this. pH + pOH = pKw = 14 Then OH^- from pOH = -log(OH^-)

chamistry
The vacancy fraction of a particular metal is found to double as the temperature of the metal is increased from 700 degrees C to 850 degrees C. Calculate the enthalpy of vacancy formation for this metal. Express your answer in units of eV.

chamistry
33.6% w/w HCl means 33.6 g HCl/100 g solution which means 33.6 g HCl/(33.6g HCl + 66.4 g H2O). moles HCl = 33.6/molar mass HCl. moles H2O = 66.4/molar mass H2O. XHCl = moles HCl/total moles. XH2O = moles H2O/total moles.

Chamistry
I am currently doing a lab write up and i have a little problem with some ionic equations the question goes as follows: You are provided with aqueous solutions of CaCl2, AlCl3, ZnCl2, CuCl2, FeCl2 and FeCl3 in six separate test tubes. To each of the solutions add 2-3 drops of ...
