Answer:
a. Decomposition.
Explanation:
A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.
- Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
- A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
- A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Hence, the answer is a decomposition reaction.
Well, that's really your place to figure out:)
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.
Answer:
It provides the electrons that "make" electricity and it contains the electrons that are involved in molecular bond formation.
