The reason why iron oxide has more mass than the iron is because Iron oxide has oxygen atoms, and pure iron does not.
When iron rusts and forms iron oxide, the iron oxide has more mass than the iron. Which statement correctly explains this
observation?
(A)Iron oxide has oxygen atoms, and pure iron does not.
(B)The oxygen atoms in iron oxide have more mass than the iron atoms in pure iron.
(C)The iron atoms in iron oxide have more mass than pure iron.
(D)There are more iron atoms in iron oxide than in pure iron.
When a chemical reaction takes place, other atoms are combined with pure elements to form compounds. This addition of another atom (oxygen) after reaction makes iron oxide formed heavier than pure iron.
Iron oxide is a chemical substance formed when pure iron rusts. The formation of iron oxide is a chemical reaction.
Hence, the correct answer to the question is; the iron is heavier because Iron oxide has oxygen atoms, and pure iron does not.

Prepositional phrases express position and relation in space and time and begin with a preposition. The only prepositional phrases here are 1) "in the house," 2) "through the tunnel," and 3) "in 45 minutes." So, whichever of these are underlined in the problem, the corresponding sentences are the answers. Hope that helps!

<h3>What is a
3D Maps tour?</h3>
A 3D Maps tour can be defined as a software program which is designed and developed to show a time-based relationship that exist between geographic locations and their associated data such as:
- Degree of temperature (highs or lows).
In a 3D Maps tour, tours and scenes are typically used to save the 3D Maps visualizations of a data set and as many tours as needed can be created in a workbook.
However, an end user can add a limit of 10 scenes to a tour depending on the situation and data.
