Question- A 1.00 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 100.0 mL of 1.00 M HCl. The Ka for HF is 3.5x10-4.
Explain each and every step in detail. I need proficient help in the above problems.
How many microcoulombs are required for complete oxidation of glucose in 0.300 microliter of blood in a home glucose monitor if the concentration is 1.00 g/L
Question- A pot of water at the boiling point (100C) contains 8200g of water. It is allowed to cool to room temperature (25C). How much thermal energy (heat) is given off in the cooling process
