To be able to answer this item, one needs to use the proper dimensional analysis such that we arrive to the same unit of measures as given in the item. If we let x be the amount, in grams, of the certain substance then, we may use the equation,

                  409.20 kJ = (x g)(1 mol/59.25 g)(1430 kJ/mol)

The value of x from the equation is 16.95 g.

Answer: 16.95 g

Which half-reaction correctly shows the oxidation of iron
pishuonlain [190]

Answer:

What is the oxidation half reaction for iron?

The two elements involved, iron and chlorine, each change oxidation state; iron from +2 to +3, chlorine from 0 to -1. There are then effectively two half-reactions occurring. These changes can be represented in formulas by inserting appropriate electrons into each half-reaction: Fe2+ → Fe3+ + e.

Hope this helps..
