I really need help! ((The balanced equation is attached))

a. Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction & which is the reduction reaction.

Cause its being chemically applied?

Answer:

5.6⋅10−^19  j

do you need the explaination?

Its the second one nonmetals are moldable and easily shaped 

Answer is: value of q is 5·10⁻⁶m.chemical reaction: mg²⁺(aq) + co₃²⁻(aq) → mgco₃(s).c(mg²⁺) = 2.5·10⁻³ m; concentration of magnesium cations.c(co₃²⁻) = 2.00·10⁻³ m; concentration of carbonate anions.q = c(mg²⁺)  · c(co₃²⁻).q = 2.5·10⁻³ m  · 2.00·10⁻³ m.q = 5·10⁻⁶m.q = 0.000005 m.
