Answer:
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4
Explanation:
The unbalanced equation is given as;
Na2B4O7 + H2SO4(aq) + H2O → H3BO3(s) + Na2SO4(aq)
Balancing the equation of the reaction involves making sure the number of moles of elements in the reactants to be equal to the number of moles of the element of the products.
The balanced equation is given as;
Na2B4O7 + H2SO4 + 5H2O → 4H3BO3 + Na2SO4

Answer: water has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will ´´want´´ to have the smallest possible surface area. The shape that has the smallest possible area for a given area is a sphere.
