Question

If one of the reactants in a reaction is Na2O, what is known about the products?

Answer 1

Answer:

The products will have at least 2 Na atoms and 1 O atom.

Explanation:

Answer 2

D. The products will have at least 2 Na atoms and 1 O atom.

Further explanation

If we refer to the law of mass conservation, which states that

In a closed system, the masses before and after the reaction are the same

then the number of atoms in the reactance will be the same as the number of atoms in the product

In this problem it is known that Na₂O is one of the reactants so that the product of Na atoms and O atoms will at least equal the number of atoms in the bond, namely 2 Na and 1 O

Like an example of this Na₂O reaction:

Na₂O + H₂O ⇒ 2 NaOH

Na : left =2, right = 2

O : left=2, right = 2
