Yes it is polluting the river with everything the manufaturing plant gives off such as the chemicals released in the air
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
This is the same as its freezing point
hope this helps
H2O+Fe⇒Fe2O3+H2
When it is balanced it would be:
3H2O+2Fe⇒Fe2O3+3H2
When balancing equations, you have to make sure that all elements are equal on each side.
