Low concentration replicate samples of Cd-EDTA gave the following counts in a mass spectral measurement: 178.3, 131.2, 144.3, 159.3, 128.3, 197.7, 149.3, 153.9, 143.3, 160.9. Ten measurements of a blank had a mean of 27.7 counts
76 g of Cr2O3 and 27 g of Al completely react to form 51 g of Al2 O3, how many gram of Cr are formed?
When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate of come apart. The resulting dissolved ions are electrically charged particles that allow the solution to conduct electricity.
