In some industrial processes, sulfite is added to remove dissolved O2 to prevent corrosion of pipes. Write the balanced overall chemical reaction for reduction of dissolved O2 by sulfite (SO32-).
assuming that the atomspher is locally isothermal, the air density variation with pressure is giving by B=B0*(P/P0) where B is density ,p is pressure , and the subscript 0 denotes conditions at the earth's surface.
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
