Aleks g for each reaction, write the chemical formulae of the oxidized reactants in the space provided. write the chemical formulae of the reduced reactants in the space provided. fe

(a) Iron metal is oxidized, lead(II) cation is reduced;

(b) Silver cation is reduced, magnesium metal is oxidized;

(c) Copper(II) cation is reduced, magnesium metal is oxidized.

Explanation:

The original question from ALEKS contains 3 reactions, we'll use them to illustrate the concept as well:

(a) ;

(b) ;

(c)

Using the abbreviation OILRIG, we know that oxidation is loss, reduction is gain (of electrons).

(a) We start with Fe at oxidation state of 0, as it's not bonded to anything and end up with iron(III) nitrate, iron has a charge of 3+ in this compound, as nitrate has a charge of 1- and 3 nitrate anions should be balanced by 3+:

Iron metal loses 3 electrons, so it's oxidized.

Similarly, we start with lead with a charge of 2+ and end up with solid lead which is neutral:

Lead(II) cation gains electrons, so it's reduced.

(b) Similarly, in this reaction we notice:

Silver cation gains an electron, it's reduced.

Magnesium metal is oxidized, as it loses electrons.

(c) Similarly:

Copper(II) cation gains 2 electrons, so it's reduced.

Magnesium metal loses 2 electrons, so it's oxidized.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
