Question 3 1 pts
Consider the following reaction:
2 PbO (5) 2 Pb(s) + O2(8)
What is the total volume of Oz produced when 1 mole of Pbo
decomposes at STP?
44.8L
11.2 L
22.4L
05.6L

explanation:

i think option no d is the correct answer

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
