Write the hode reaction in electrolytic reduction of

Answer. The positively charged aluminium ions ( Al3+) are attracted to the hode (negative electrode). The aluminium ions accept electrons from the hode and get reduced to form aluminium atoms (or aluminium metal).

21.2 Nuclear Equations – Chemistry - opentextbc.ca

The nuclear reaction can be written as: 25 12Mg + 4 2He 1 1H + A ZX 12 25 Mg + 2 4 He 1 1 H + Z A X. where A is the mass nuer and Z is the atomic nuer of the new nuclide, X. Because the sum of the mass nuers of the reactants must equal the sum of the mass nuers of the products: 25 + 4 = A + 1, or A = 28 25 + 4 = A + 1, or A = 28.

The numeric values for this example have been determined experimentally. A mixture of gases at 400 °C with [H 2] = [I 2] = 0.221 M and [HI] = 1.563 M is at equilibrium; for this mixture, Q c = K c = 50.0. If H 2 is introduced into the system so quickly that its concentration doubles before it begins to react (new [H 2] = 0.442 M), the reaction will shift so that a new equilibrium is reached
