Explanation:

i got it right on edge

To balance a reaction means to make the number of atoms the same on both the reactants and products side. The steps for balancing is as follows:-

  • Balance the Metal first
  • Then balance the Hydrogen
  • Balance the oxygen at last

According to the question, there are third reactions. the reaction third has the 3 coefficient before the compound.

The balanced reaction is as follows:-

[tex]3H_2So_4 + 2B (OH)_3------->B_2(So_4)_3 + 6H_2O[/tex]

Hence the correct compound is[tex]3H_2SO_4[/tex].
