Calculate the moles of solute needed to prepare each of the following: 3.5L of a 1.4M CaCl2 solution, 4.5L of a 0.10M NaOH solution, 250ml of a 3.6M HNO3 solution.
If the spectrophotometer that was used was miscalibrated so that each absorbance reading was too high by 0.100 units
Write the balanced equation for the hydration of CuSO4. Indicate the physical states using the abbreviations (s), (l), or (g) for solid, liquid, or gas, respectively
The amount of lead in a aqueous sample is determined by atomic absorption spectrometry. Two standard solutions are prepared and used to make a calibration curve, and then the absorbance of the sample is measured.
The equilibrium amounts would stay the same the equilibrium would shift to the right making more reagents the equilibrium would shift to the left making mroe reagents the equilibrium would shift to the right making more products the equilibrium wo..
