A zero-order reaction has a constant rate of 2.00×10-4 . If after 50.0 seconds the concentration has dropped to 6.00×10-2 , what was the initial concentration?
How do the brilliant colors( purple) of these transition metal complexes (i.e. Cobalt hexhydrate) relates back to the UV-Vis spectrum recorded
Would a solution that has a molarity of 0.990 M KNO3 and a density of 0.988 g/mL be considered unsaturated, saturated, or supersaturated?
A solution is prepared by mixing 63.0 mL of 5.00 M HCl and 20.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
