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.

Answer:
D. Spend quality time with the kids first when she is back home before resuming any other work.
Explanation:
The value of the first term of the sequence is 0.
<u>Given the following data:</u>
To find the value of the first term of the sequence:
In this exercise, you're required to determine the first term of a sequence by using the given sequential equation.
In order to do this, we would substitute the value of n.
<u />
- <u>Note:</u> The first term of a sequence is n equal to one (1).
Substituting the values into the equation, we have:
Therefore, the value of the first term of the sequence is 0.
