When 1mol of HCl reacts with 1mol of NaOH, 1000 k/cal of heat is produced. How much energy is released when 20g of NaOH is reacted?
-
Moles of NaOH = 20/40 = 0.5
So when 0.5 moles of NaOH will react with 0.5 moles of HCl, energy released = 500 kcal
So when 0.5 moles of NaOH will react with 0.5 moles of HCl, energy released = 500 kcal
