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 tension on each segment of the clothesline is : 110 N
<u>Given data : </u>
mass of object = 100 n = 10 kg
Horizontal distance of clothesline = 4 m
middle of clothesline sag s by : 1m
<h3 /><h3>Determine the tension on each segment of clothesline</h3>
<u>First step</u> : calculate the horizontal angle made by the sagging
β = arctan ( 1 m / 2m ) ----- ( 1 )
= arctan ( 0.5 )
≈ 26.57°
Note : Tension in th y axis ( Ty ) = Tsinβ
Therefore :
Tension on each segment can be calculated using the formula below
2Tsinβ - mg = 0
solve for T
T = mg / 2sinβ
= ( 10 * 9.8 ) / 2 * sin 26.57°
= 98 / 0.89
= 110 N
Hence we can conclude that the tension on each segment of the clothesline is : 110 N

Answer:
I DONT KNOW DO YOU WANT TO BE MY FRIEND I DONT KNOW DO YOU WANT TO BE MY FRIEND
Explanation:
I would say A because the author explains on how masculine he looks and how tough he is but then it switches to him showing his affection for his wife and how he is actually soft inside.
Of course I can be wrong but hey I've never took the SAT's before
