The normal boiling point for acetone is 56.5c. At an elevation of 5300 ft the atmospheric pressure is 630.torr. Explain what would be the boiling point of acetone ( H vap= 32.0 kj/mol) at this elevation. Define what would be the vapor pressure of acetone at 25.0c at this elevation?
State a balanced reaction that describes how sodium bromide as well as sulfuric acid will produce hydrobromic acid
There is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of Magnesium metal consumed in the reaction, therefore moles of H2 evolved = moles Mg consumed and the atomic weight of Mg = weight of Mg consumed..
