In a water molecule, two hydrogen atoms bind to one oxygen atom. how many lone pairs of electrons will be shown around each hydrogen atom in the lewis structure of water?
a.) zero
b.) one
c.) two
d.) four
plato answers

A.) zero

Explanation:

In the Lewis structure of water it is formed a perfect 8 electrons around the Oxygen atom, as you know all element tend to the 8, could be by giving electrons or receiving, Hydrogen has 1 sole electron and oxygen has 6, this means that oxygen needs 2 more to complete 8, so if you add the 1 of each molecule of hydrogen they form 8 electrons, so there won´t be any loose electrons.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
