You can see that this equation is not balanced. Now, let’s balance this equation: 2NaCl + H2SO4→ Na2SO4+ 2HCl No of moles (n): (2 moles) (1 mole) (1 mole) (2 moles) So, 2 moles of NaCl react with 1 mole of H2SO4to give 1 mole of Na2SO4 and 2 moles of HCl. This means, without balancing the equation, we can’t … Ver mais So, let’s get forward with understanding the concept of gram equivalence.
