A redox reaction involves the reduction of one substance (gaining electron(s)) and the oxidation (losing electron(s)) of another. Examples of reduction and oxidation are shown.

Combine the two given reactions like algebraic equations and write the net, or overall, redox equation.

(A)⟶(A^+)+(e−) oxidation of A
(e−)+(X)⟶(X−)reduction of X

net redox equation:

A + X ⟶ A^+ + X^-

Explanation:

Add the reactants from the oxidation and reduction equations then add the products.

A + e^- + X ⟶ A^+ + e^- + X^-

Cancel any species that appear on both sides of the equation. In this case, an e^- can be eliminated from both sides which leave us with:

A + X ⟶ A^+ + X^-

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
