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

B) 1,2,1,2

Explanation:

The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

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

Efficiency is an action of doing something. for example when you take a test. good efficiency means you did well but bad effeciency or no effiency means you did bad.
