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.

Matter becomes energy. Law of thermodynamics states that matter can't be created or destroyed, but can transfer to another form. If it was closed in with the form of energy, it would be transferred to the form of energy.
I'm pretty sure it's A
Explanation:
I did a few quick Google searches on ap classes because I myself do not take them a I read that most colleges do take ap classes as credit. it's no guaranteed however as it says many, not all. and for C I looked it up and I'm assuming they can be taken anywhere. take what I say with a grain of salt though because like I said I just googled it, hope it helps though.
After defeating the Spanish armada, the British settlers settled along the eastern coast claimed all territory from newfoundland to Florida for the king .
In particular, the planting of a colony at Cuppers Cove (Cupids, Conception Bay) by the London and Bristol Company in 1610 and the southern Avalon plantation in the early 17th century was responsible for the first British settlement in Newfoundland.
Between Trespassed in the south and Salvage in the north, there were at least one family in 30 distinct villages along Newfoundland's east coast by the 1670s.
Following the defeat of Spanish Armada, they settled in Newfoundland, which typically included a period of apprenticeship servitude.
