In a chemical reaction, atoms are rearranged to form new substances. This point happens predictably. The same reactants will form the same products no
matter when or where the reaction takes place. For example, in a lab, you
could combine iron and oxygen. The product will be the same iron oxide
that forms on a rusty iron nall. Those are the same reactions, Similarly, if
you've studied acids and bases, you probably know the products of a
neutralization reaction. Acids and bases will combine in a chemical reaction
to produce a salt and water. Based on the passage, rust will form on an iron
nail when what has occurred?
a neutralization
an acid has combined with a base
ООО
salt has reacted with water
O iron has reacted with oxygen
