Is the reaction in a 'glow-stick' reversible or irreversible?

Chemistry

Glow sticks are sold with a solution of oxalate and dye being in one vessel and a solution of hydrogen peroxide contained in another vessel. By bending the sticks, the inner vessel breaks. This allows the two solutions to mix and react with each other, leading to chemiluminescence. Since the reaction is not reversible, the glow sticks can only be used once.

how many moles of sodium are needed to react with sulfuric acid to produce 3.75 moles of sodium sulfate according to the followi
anastassius [24]
Hello!
<span>
You'll need to react 7,5 moles of Sodium with sulfuric acid to produce 3.75 moles of sodium sulfate
</span>
First of all, you need to balance the reaction. The balanced reaction is shown below (ensuring that the Law of Conservation of Mass is met on both sides):

2Na + H₂SO₄ → Na₂SO₄ + H₂

Now, all that you have to do is to use molar equivalences in this reaction applying the coefficients to calculate the moles of Sodium that you'll need:

molesNa=3,75moles Na_{2} SO_4* \frac{2 moles Na}{1 mol Na_{2} SO_4} =7,5 moles Na 

Have a nice day!
