Outline the way in which the Health and Safety at Work Act (HASAW ACT) 1974 controls work place health and safety. Compare HASAW Act with Occupational health and safety regulations of Sultanate of Oman. and give an outline of what would be needed to set up a suitable safety management system to control the hazards in a chemical process industry?
And, of course, ammonia is a base so there will be some NH4+ in solution also. Assume that the concentration of unprotonated NH3 is 0.040 M. What fraction of the cadmium ions are in the form of Cd2+
What is the final concentration (in M) of 19.5 mL potassium hydroxide solution with an initial concentration of 1.85 M which is diluted with 16.8 mL of solvent? Assume the volumes are additive.
A student used 20.0 mL of 0.1035 M NaOH to titrate 20 mL of orange juice. How many grams of citric acid were present in the sample? The molar mass of citric acid, H3C6H5O7, is 192.12 g/mol.
At 8:00 a.m., a patient receives a 58-mg dose of I -131 to obtain an image of her thyroid. If the nuclide has a half-life of 8 days, what mass of the nuclide remains in the patient at 5:00 p.m.
