(i) Hydrogen chloride gas is prepared by treating Sodium chloride with concentrated sulphuric acid. The HCl gas is passed through a drying agent to remove moisture where concentrated sulphuric acid plays the role of dehydrating agent as well.
Can be prepared by reacting methanol with hydrogen iodine and adding carbon monoxide to the product ( methyl iodide) in order to obtain acetyl iodide. Upon hydrolysis , acetyl iodide yields acetic acid. Acetic acid and chlorine will react a Chloroacetic acid will be formed. CH3COOH+Cl2 gives rise to CICH2CO2H. Second example : when acetic acid is heated with phosphorus pentachloride , acetyl chloride is obtained. In this reaction : COOH group is converted to COCI group. The side products are phosphorus oxychloride and HCI Third example: Ethanol and acetic acid react to form ethyl acetate and water according to the equation: C2H5OH + CH3COOH CH3COOC2H5 + H2O when 2 moles each of ethanol and acetic acid are allowed to react at 100 degrees Celsius in a sealed tube, equilibrium is established when 2/3 of a mole of each of the reactants remains.
Thecinically it is both because and an un opened bottle of soda is homogeneous and an opened bottle of soda is herterogeneous. I hope this helps please reward branlist.
60 elements! I don't exactly know every element known, so if you are asking that, please tell us, but what I do know is that there were 60 elements in the periodic table by 1860.
