Sulfuric acid, H2SO4, can be neutralized by sodium hydroxide, NaOH. The unbalanced equation is: H2SO4(aq) + NaOH(aq) → Na2SO4(aq) + H2O(l)

A student who was asked to balance the reaction wrote the following:

H2SO4(aq) + Na2OH(aq) →Na2SO4(aq) + H3O(l)

Is this correct? Explain why or why not using what you know about the law of conservation of mass and chemical changes. If necessary, provide the correct balanced equation. (5 points)

This equation is incorrect because you can only add coefficients or molecules of the substance. For example, you can't just change H20 (Water) to H3O (Hydronium) which is a different compound. The same thing goes for Na2OH.

The correct balanced equation is:

H2So4(aq) + 2 NaOH(aq) = Na2So4(aq) + 2 H2O(l)

Remember, you can only add more molecules of a substance (coefficients) not change the formulas (subscripts).

where is the following

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.
