1. Why fractional distillation has<br> fractionating column but not in simple<br> distillation?
egoroff_w [7]

Answer:

  • <em>Fractional distillation leads to a better separation than simple distillation because the glass beads in the fractionating column provide "theoretical plates" on which the vapors can condense and then re-evaporate, and re-condense, essentially distilling the compound many times over.</em>

69g of sodium reacts with chlorine to produce sodium chloride. calculate the number of moles of chlorine required to react with
Rus_ich [418]

Answer:

3 moles of Cl^{-} is needed for Na^{+}to be fully consumed.

Explanation:

For the balanced equation:

                                  Na^{+}  +  Cl^{-}  ⇒  NaCl

First, find the moles of Na corresponding to the 69g used the general definition of mol:

                               mol Na^{+} = \frac{69 g}{23 g/mol }  = 3mol

We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.

According to this, one mole of Na will react with one mole of Cl.

                3 moles of Cl^{-} is needed for Na^{+}to be fully consumed.
