Question

Which is an incorrect interpretation of this balanced equation? 2s(s) + 3o2(g) → 2so3(g) 2 mol s + 3 mol o2 → 2 mol so3 2 g s + 3 g o2 → 2 g so3 2 atoms s + 3 molecules o2 → 2 molecules so3?

Answer 1

The correct answer is the option a: 2 mol s + 3 mol o2 → 2 mol so3

Step-by-step explanation:

Hello!

Let's solve this!

The reaction is:

2s (s) + 3o2 (g) → 2so3 (g)

This means that as reagents we have 2 moles of sulfur, 3 moles of oxygen (the oxygen molecule is composed of two atoms of the element) and the product is 2 moles of sulfur trioxide.

Therefore, the correct answer is the option a: 2 mol s + 3 mol o2 → 2 mol so3

Answer 2

Answer is: 2 g S + 3 g O₂ → 2 g SO₃, chemical reaction is not balanced with mass.
1) 2S(s) + 3O₂(g) → 2SO₃(g). Chemical reaction is balanced, equal amoont of atoms on right and left side of reaction.
2) 2 atoms S + 3 molecules O₂ → 2 molecules SO₃. Correct chemical reaction interpretation.
