Marina CMI [18]
I’m pretty sure you would have to divide 5 and 30 and you will get 0.16666666 but I would think it would be 6cm/s but I could be wrong and if it is I’m am truly sorry.

Balancing H2SO4+NH4OH —&gt; H2O+(NH4)2SO4
azamat

H₂SO₄   +    2NH₄OH    →     (NH₄)₂SO₄   +    2H₂O

Explanation:

  Unbalanced reaction equation:

                    H₂SO₄   +    NH₄OH    →     (NH₄)₂SO₄   +    H₂O

We can use a simple mathematical approach to balance this equation by solving simple algebraic equations.

         aH₂SO₄   +    bNH₄OH    →     c(NH₄)₂SO₄   +    dH₂O

a,b,c and d are simple coefficients that will balance the equation:

   Conservation of H: 2a + 5b = 8c + 2d

                               S:   a = c

                               O:  4a + b = 4c + d

                               N:   b = 2c

lets assume that a = 1

                             c= 1

                             b = 2

                  Solving for d from 4a + b = 4c + d

                   d = 4a + b -4c = 4(1) + 2 - 4(1) = 2        

 

                  H₂SO₄   +    2NH₄OH    →     (NH₄)₂SO₄   +    2H₂O
