What is the boiling point and freezing point of a 2.21m alcl3 aqueous solution? (the kf=1.86c/m and kb=0.512c/m)

What is impossible to do with a hypothesis

Which statement about hf is true? it is zero for any compound in its standard state. it is positive when the bonds of the product store more energy than those of the reactants. it is negative when a compound forms from elements in their standard states. it is zero for any element that is in the liquid state.

Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )
