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.

The constructed proof is given below.
<h3>Calculations and Parameters</h3>
Prove: f(M)= 7M +4 is not divisible by 7 for any integer M.
M=0 --> f(M) = 4 which is not divisible by 7.
M=1 --> f(M) = 11 which is not divisible by 7.
Suppose f(M) is not divisible by 7 for some positive integer M.
(this is the GIVEN induction hypothesis)
7(m+1)+4 = 7m+7+4 = 7m +4 + 7 = (7m+4)+7
dividing by 7, the quotient is [(7m+4)+7]/7
= (7m+4)/7 + 1
This is NOT divisible by 7 per induction hypothesis...

- A split infinitive is often occurs when other words come between the two parts of the infinitive.They may look informal and result in confusion.
- Split infinitive in a sentence can be handled by the rearrangement of the the sentence so that nothing is between the two parts of the infinitive.
Conclusively, we can say that split infinitive sometimes look informal and may result in confusion but it can be handle by rearranging the sentence.
