Precipitation reaction is a chemical reaction used to separate the insoluble solid to the aqueous solution. This is a technique that is usually used to separate the impurities. By knowing the right chemical to react with, only the pure acid will react and dissolve with ether. The impurity will be precipitated and will settle to the bottom.
I have no formula however the process would be erosion... copper is a type of metal and when it rots from water or any type of liquid damage it erodes and gets that green coat.
Bruhhhhhhhhhhhhhhhhhhhhhh

Hello, this question is incomplete. The complete question would be:
"Write the balanced chemical equation for the following reaction.
Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water"
Answer:
Fe2O3 + 3 H2 = 2 Fe + 3 H2O
Explanation:
In a chemical reaction, the structure of atoms as chemical elements is unchanged. Atoms in one element do not become atoms in another element. There is also no loss or creation of new atoms. The number of atoms of the reagents must be equal to the number of atoms of the products. When this happens, we say that the chemical equation is balanced.
For this reason, we can state that the balanced chemical reaction where solid iron (III) oxide reacts with hydrogen gas to form solid iron and liquid water would be:
<em>Fe2O3 + 3 H2 = 2 Fe + 3 H2O
</em>
