Calculate the pH of a solution prepared by dissolving 1.30 g of sodium acetate, CH3COONa in 92.0mL of 0.15 m acetic acid, CH3COOH(aq) assume the volume change upon dissolving the sodium acetate is negligible. Ka of CH3COOH is 1.75 x 10^{-5}

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.

The answer is nitrogen-containing bases
