Explanation:
2nacl+baso4
the orginal equation is
Na2so4+Bacl2
then na react with cl and ba react with so4
Answer:
C
Explanation:
the enthalpy of reaction is independent of the reaction path
Because you’ll fall in the water.
In the first distillation this week, Hexane from the original solvent makes a larger contribution to the vapor pressure of the mixture.
In between hexane and toluene, the hexane will have more vapor pressure contribution in the solution. The boiling point of hexane is much lower than toluene. Therefore, it will evaporate easily at low temperatures and start exerting pressure on the solution.
Hence between hexane and toluene, because of more vapor pressure of hexane and lower boiling point, it will easily evaporate and exerts pressure.
Therefore, from the original solvent, hexane makes a larger contribution to the vapor pressure of the mixture.
