When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this difference in mass?(1 point) Responses There are more iron atoms in iron oxide than in pure iron. There are more iron atoms in iron oxide than in pure iron. The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron. The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron. The iron atoms in iron oxide have more mass than pure iron. The iron atoms in iron oxide have more mass than pure iron. Iron oxide has oxygen atoms, and pure iron does not.

Answer 1

The correct statement that explains the difference in mass is: Iron oxide has oxygen atoms, and pure iron does not.

When iron rusts, it reacts with oxygen in the air to form iron oxide (rust), which includes both iron and oxygen atoms, resulting in a greater mass compared to the original iron alone.
