In the reaction at Blood Falls, iron and oxygen combine to form iron oxide, which is called rust (water is also present). The reactants are , and the product is

The reactants for rust are iron ,water and oxygen while the products are hydrated iron oxide

Explanation:

4Fe+3O2+2H2O>2Fe2O3.H2O

here are the answers for the following parts:

1) In the reaction at Blood Falls, iron and oxygen combine to form iron oxide, which is called rust (water is also present). The reactants are

oxygen and iron and the product is iron oxide.

2) How do you know there was a chemical reaction? Check all indicators below.

A solid precipitate formed.

The color changed.

A gas was produced.

The reaction absorbed or released heat.

3) 4Fe + 3O2 + xH2O → 2Fe2O3 • xH2O

The formation of rust (equation above) is an example of both combustion and synthesis.

your answer is c) plasma
