This is a diagram showing the process of distillation of salt water into pure water. where is the pure water in the diagram?

Distillation is the process of separating a mixture of liquids, or a mixture of solid (dissolved salt in this case) and a liquid (water), advantage taken of the difference in boiling points of the ingredients.

In the diagram, the salt water is placed in flask A and heated using a gas (or Bunsen) burner.  Water is converted to steam and passes through the fractionating column B, which is normally required only for separating two liquids of close boiling points.  The vapour is then passed through the condenser (or Liebig condenser as some are called) C which condenses the water vapour back into liquid form.  Note that the cooling water enters at the bottom and leaves the conderser from the top, according to the counter-current principle.  The condensed liquid, pure water in this case, will then drip down into the conical flask D on the right.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
