Answer:

B: Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)

Explanation:

We are looking for enthalpy of formation, so we want to see reactance in their natural standard form.

Thus, we want to see the reactance of Na, Cl2 and O2.

The only option that has the correct form of Na, Cl2 and O2 is B.

Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)

At STP, when 3.75 liters of oxygen reacts with excess glucose, what volume of carbon dioxide does it produce?

yKpoI14uk [10]

Well, STP means standard temperature and pressure

In this condition, it is safe to assume that the moles of specie given will be equal to the moles of specie sought

I think the volume of the Carbon dioxide that it produced will also be 3.75 liters

Hope this helps
