Question- Calculate the freezing point of a solution that contains 30.8 g of urea, CH4N2O (MW = 60.06 g/mol), in 196 g of water. Urea is a nonvolatile nonelectrolyte. Kf for H2O = 1.86°C/m.
Please provide the answer of the given question on urgent basis
They provide an alternative path for protons to re-enter the mitochondrial matrix, so ATP synthesis decreases. Electron flow and proton pumping are not inhibited.
Phthalocyanine is a large molecule used in printing inks and dyes for clothing due to its insolubility in most solvents, its chemical stability, and its intense blue color.
