Question

What coefficients must be added to balance the following equation?

_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O

2, 1, 1, 1
3, 1, 1, 3
2, 1, 1, 2
4, 2, 2, 1

...?

Answer 1

The answer is C 2,1,1,2

Answer 2

To balance a chemical reaction it is important to remember that the atoms of each element in the reactant and the product side should be the same or equal in number. Therefore, the correct answer is the first option. The balanced equation is:

2NaOH + H2 SO4 -----> Na2SO4 + H2O

Hope this answers the question. Have a nice day.
