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.

Sulfuric acid, H2SO4, can be neutralized by sodium hydroxide, NaOH.

Explanation:

The balanced chemical equation of the reaction is:

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

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

This is wrong equation.

Because, the formula of sodium hydroxide is NaOH only and it is not .

Because the valency of sodium will not exceed one and hydroxide ion has valency is also one.

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

for this equation, the left side mass of reactants is:

161.0g

Right side mass of products is:

161.0 g

But H3O(l) will not exist and will exist.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
