The given question is incomplete. The complete question is:
The combustion of propane (C3H8) in the presence of excess oxygen yields
and
When only 2.5 mol of
are consumed in order to complete the reaction, ________ mol of
are produced.
Answer: Thus when 2.5 mol of
are consumed in their reaction, 1.5 mol of
are produced
Explanation:
The balanced chemical equation is:
![C_3H_8(g)+5O_2 (g)\rightarrow 3CO_2(g)+4H_2O (g)](https://tex.z-dn.net/?f=C_3H_8%28g%29%2B5O_2%20%28g%29%5Crightarrow%203CO_2%28g%29%2B4H_2O%20%28g%29)
According to stoichiometry :
5 moles of
produce = 3 moles of ![CO_2](https://tex.z-dn.net/?f=CO_2)
Thus 2.5 moles of
will produce =
moles of ![CO_2](https://tex.z-dn.net/?f=CO_2)
Thus when 2.5 mol of
are consumed in their reaction, 1.5 mol of
are produced
No, because the appearance has nothing to do with system as well as the fact that appearance is only how it looks
