Answer:
My claim is the iron pipes and the fertilizer changed into rust. In the activity with tokenes, rist could not form without the iron atomes frome the pipe and the oxygen atoms from the fetilizer . this evedince matters because substances changes into defffrint sub durning a chemical eaction. during the chemical reaction the atoms of the reactants rearange to form repeating groups of atoms that make up the produst for this reason the atoms that make up the product mist be presents in the reactants without theses atoms the products cannot from through rearrangement. Rust cannot from form just teh iron atoms foorm the pipes since the reapering groups of atoms that make up rist include oxygen atoms. Similarly, rust cant from form just the nitrogen sodium and oxygen atoms from teh fertilizer because the reapeating groups of atoms that make up rist include iron atoms. My modle shows how the two iron atoms from the pipes and the three oxygen atoms from the fertilizer can rearrange to form rist. Therefore, there must have been a chemical reactin in wich the iron pipess and the fertiliser changed into rust.
