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)

Answer 1

It is not correct

Step-by-step explanation:

there is no Na2OH because OH is -1 and Na is +1

there is no H30 because oxygen can only have 2 bonds with hydrogen

the balanced equation is:

H2SO4 + 2NaOH => Na2SO4 + 2H20
