Question

fill in the blanks in the sentence below.
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

Explanation:

In a chemical reaction, reactants are the substances that undergo the reaction, and the product is the substance formed. From the given reaction, iron (Fe), oxygen (O₂), and water (H₂O) are the reactants (since the problem mentions iron, oxygen, and water is present), and iron oxide (rust, \(Fe_2O_3\) or related iron - oxygen compounds) is the product. But based on the sentence structure, for the first blank (reactants), we consider the main reactants mentioned in the combination: iron, oxygen, and water (but the problem's context might be simplifying, and the key reactants for the formation of iron oxide are iron, oxygen, and water; however, the sentence says "iron and oxygen combine to form iron oxide (water is also present)", so the reactants are iron, oxygen, and water, and the product is iron oxide (rust).

Answer:

For the first blank (reactants): iron, oxygen, and water
For the second blank (product): iron oxide (rust)
