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:
It can be represented by the conditional statement:
"If it is an acute angle then the angle is less than 90°"
A conditional statement is a statement that takes the form of “If P then Q,” For P is called the hypothesis and Q is called the conclusion. Also, both P and Q are sentences.
Given the sentence: All acute angles have measures less than 90°
It can be represented by the conditional statement:
"If it is an acute angle then the angle is less than 90°"
