Find the normal boiling point of a saturated solution of LiF at 100 ? C, assuming it un- dergoes complete dissociation. The solubility of LiF is 230 mg/100 g of water at 100?C, and the boiling point constant of water is 0.51 K · kg/mol.
If the actual pressure of the vapour was less than the surrounding , will molecular weight you determine (heptane) be too low or too high
The product is a cyclopentyl ether (five carbons with an oxygen). Then attached to a carbon directly adjacent to the oxygen is a methyl bromide group.
How much heat (in kJ) is evolved in converting 1.00 {mol} of steam at 160.0C to ice at -45.0C? The heat capacity of steam is 2.01 J/g*C and of ice is 2.09 J/g*C.
What are 3 most significant structural differences between HPLC equipment and Ion Chromatography instruments
Cryolite (Na3AlF6) is an indispensable component in the electrochemical manufacture of aluminum. draw a lewis structure for AlF6 3- ion.
Find out What mass of the NaHCO3 reacts with the vitamin C When the tablet dissolves in H2O, it "fizzes" because the reason for this is the CHO3 reacts with the citric acid(C6H8O7 a weak organic acid) and the vitamin C?
Given the following balanced chemical equation Ca(OH)2+2HCl-->CaCl2 +2H2, if 56.7g of calcium hydroxide react completely, how many g or HCl also reacted
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range. Its solubility in urine depends on the relative amount of protonated and unprotonated forms. A urine sam..
