  • A mineral is an inorganic compound that is formed naturally.
  • They have a definite and specific chemical composition.
  • Minerals are the building blocks of rocks.
  • When minerals aggregates together, they form different rock types.
  • There is no known mineral that is in fluid state.

During oxidation of ethanol to ethanol, the ethanol formed was found to be contaminated with unconverted ethanol, describe how y
Dafna1 [17]

<u><em>The process of how we would obtain </em></u><u><em>ethanal</em></u><u><em> </em></u><u><em>free</em></u><u><em> from ethanol is described in the explanations below. </em></u>

<u><em /></u>

  • In Chemistry, Ethanol undergoes oxidation in the presence of sodium dichromate plus sulphuric acid to yield ethanal and water.

The procedure for achieving this in the laboratory is as follows;

  • Step 1; Measure a quantity of a solution of sodium dichromate acidified in a dilute sulphuric acid and pour into a test tube.

  • Step 2; Add excess <em>ethanol</em>. This is because if we don't do so there will be plenty of oxidizing agent to carry out a second operation which changes the aldehyde to ethanoic acid. However, we need only the aldehyde.

  • Step 3; When the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from <em>orange to green</em>, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.

The compound XCl is classified as Ionic if x represents the element?
puteri [66]
Well since chlorine upon receiving a valence electron from the X element, we would know that the element would be a metal, based on the charge of Cl, after it receives a valence electron is -1, the metal would have to give 1 valence electron as well, and thus the possible elements can be any metal within the group 1 of the periodic table of elements. Lithium, Potassium etc.
