An alkaline battery produces electric energy according to this equation. Zn + 2MnO2 + H2O ---> Zn(OH)2 + Mn2O3

a. If 30.0 grams of zinc and 45.0 grams of manganese (II) oxide are reacted with excess water, what is the limiting reactant?

b. What mass of zinc hydroxide is produced by the reaction?

i do not get it   at all

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
