2NaOH + H2SO4 --> Na2SO4 + 2H2O

How many moles of H2SO4 are needed to react with 4 moles of NaOH?



4 moles H2SO4

1 moles H2SO4

2 moles H2SO4

3 moles H2SO4

Respuesta :

Answer:

Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water.  If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water.  Therefore it would take .25 moles of sulfuric acid to react with .5 moles of sodium hydroxide.

Explanation:
Answer
2moles
Explanation.
The mole ratio of NaOH:H2SO4
2: 1
That means 1mole of H2SO4 require 2moles of NaOH.
Therefore; 1—>2
—> 4
4×1=4
4÷2=2
The answer therefore is 2moles
