When weighing liquid ethanol, why do you have to place water in the beaker prior to adding the ethanol to that same beaker?
Which of the following statements describes why ion exchange of 99% SiO2 - 1% B2O3 in a salt bath of molten postassium chloride (KCl) is not an effective way to increase the surface strength of the glass sample? The ion exchange works correctly, however both air-cooling and wa...
C6H12 = 6x12 + 6x1 = 78. The equation indicates that 2x78 = 156g benzene will produce 6542kJ. Using proportions you can then calculate that x/6542kJ = 8.1g / 156g x = 339.7kJ = 339700J. heat = mass x ΔT x 4.18J/g° ΔT = 339700J / (5691g x 4.18J/g°) = 14.3°...

CCl4 ClO4− ClF4− SiCl4 SO42− Which molecule or ion does not have a tetrahedral molecular geometry?
Btw, I did it the way you said and I still come up with the same conversion of 29.8 * (760/1)= 22648
