What coefficients must be added to balance the following + so4 na2so4 + h2o 2, 1, 1, 13, 1, 1, 32, 1, 1, 24, 2, 2, 1

NaOH + H2 SO4 Na2SO4 + H2O ,

To balance this equation,

Step 1:

Balance the number of sodium on both side:

by multiplying the NaOH by 2 that is:

2NaOH+H2SO4>Na2SO4+H2O

Step2:

As NOW the number of oxygen atom and hydrogen atom are not equal on both sides. So we multiply this H2O by 2 that is:

2NaOH+H2SO4>Na2SO4+2H2O

Now the no of all atoms on product side is equal to no of all atoms in the reactant side.

so the coefficient is 2 NaOH+1 H2SO4>1 Na2SO4+2 H2O.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
