What is the molarity of the acetic acid if 0.5ml of a vinegar solution has been titrated with the 0.101M solution of NaOH and the volume of the NaOH solution at the equivalence point is 5.0mL?
I agree with Ms. Sue
At a fabrication plant, a hot metal forging has a mass of 66.8 kg and a specific heat capacity of 437 J/(kg C°). To harden it, the forging is quenched by immersion in 785 kg of oil that has a temperature of 25.0 °C and a specific heat capacity of 2770 J/(kg C°). Th...
A room has a volume of 164 m3. An air-conditioning system is to replace the air in this room every 26.8 minutes, using ducts that have a square cross section. Assuming that air can be treated as an incompressible fluid, find the length of a side of the square if the air speed ...
