Write the formula equation, the overall ionic equa- tion, and the net ionic equation for the neutralization
reaction involving aqueous solutions of H3PO4 and
Mg(OH)2. Assume that the solutions are sufficiently
dilute so that no precipitates form.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

it is a solid

explanation:

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

c) should be the answer.
