3h2so4 2b(oh)3 - b2(so4)3 6h2o what is the mole ratio between water and sulfuric acid?
Nutka1998 [239]

Since there is an equal number of each element in the reactants and products of 3H2SO4 + 2B(OH)3 = B2(SO4)3 + 6H2O, the equation is balanced.

<h3>What is Sulfuric acid?</h3>
  • Sulfuric acid (H2S04) is a corrosive substance, that destroys the skin, eyes, teeth, and lungs. Severe vulnerability can result in death. Workers may be harmed from disclosure to sulfuric acid. The level of exposure depends on
  • The sulfuric acid bleaching can substitute the presently assumed oxygen and chlorine stages if the additives are allowed. This bleaching process was also practical for oxygen-bleached hardwood kraft pulp, but it was less compelling for softwood kraft pulp and oxygen-bleached softwood kraft pulp.
  • Disbanding sulfuric acid in water is an exothermic procedure. When sulfuric acid is mixed with ice this exothermic procedure causes the temperature to rise at first, but as more of the ice dissolves, the temperature falls.

Entropy is the tax we pay for borrowing nature's power.discuss​
Alexxandr [17]

Answer:

Explanation:

Entropy is the thermal energy that is unavailable for humans to do useful work.human system normally progress from disorder to order. This entropy interferes with humans day to day activities. Once this energy is consumed it is converted from one form to another and it is the tax paid for those energies. It is the continuous dissipation of energy. For example if 1000J of energy is consumed, and nature take part of it, 900J is available for work.
