L.39 Fundamental Question

Postby Connie Liang 3L » Sat Oct 24, 2020 9:30 pm

Part of the question reads "A 1.27-g sample of metallic copper was placed in a 26.32-g crucible and heated until all the copper had reacted with the oxygen in air to form an oxide."

I was wondering if oxygen in the air is the same thing as oxygen gas. So would "oxygen in air" be the same thing as O2?

Yes, that is what I used to find the empirical equation for the problem.

Yes I agree that the oxygen in the air is the same as oxygen gas. Naturally, oxygen appears in a pair just like H, N, Cl, Br, etc. Hope this helps!

Yes, oxygen air would be oxygen gas! Oxygen is a diatomic particle, so it would be written as O2.
