Question

H2SO4 + NaOH > Na2SO4 + H2O. Balance this reaction if necessary. A) balanced B) 1,2,1,2 C) 1,2,1,4 D) 1,2,2,2

Answer 1

B) 1,2,1,2

Step-by-step explanation:

• The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

• The equation for the reaction is balanced by using coefficients; 1,2,1,2

• According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.
• For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
