Pb(OH)2, PbCl2 d. Ni(NO3)2, Ni(CN)2What is the name of the compound BaCrO4? Is it an insoluble, moderately soluble, or very soluble salt?Potassium chloride has solubility 43.0 g/100 g water at 50 degrees C. Will a mixture of potassium chloride (...
Why is PF2Cl3 non-polar and PF3Cl2 polar? Why is it bad to add boiling H_2O to ethanol solution during aspirin recrystallization? Also, provide a mechanism for the production of aspirin from salicylic acid and acetic anhydride without the use of an acid catalyst. ...
A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bond dipole moments occur due to differences in electronegativity. Answer and Explan...

（）（10分）工业上制备BaCl 2的工艺流程图如图： 某研究小组在实验室用重晶石（主要成分BaSO 4）对工业过程进行模拟实验。查资 料得： BaSO 4(s) + 4C(s) 4CO(g) + BaS(s) ΔH 1 = +571．2 kJ·mol -1 ① BaSO 4(s) + 2C(s) 2CO 2(g) + BaS(s) ΔH 2= +226．2 kJ·mol -...
That's the polyatomic ion, Hg--Hg bonded to the other(s) then we'd have a formula of Hg2Cl2 because the formula for an ionic compound, is simplest ratio of ions, not simplest ratio of atoms.And still supposing it were an ionic compound, then judging by the formula, it wouldn't ...
I am trying to evaluate data in a cell array to input into a new matrix/array. I am simply attempting to evaluate whether values in a cell array are less than a specific number or not. If it is less than, I store 1, if it is greater than, I store 0 in a...
