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:
Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.
Explanation:
Krypton (₃₆Kr), an element with atomic number 36, belongs to group 18 on the periodic table of elements. This group is a specific one - it's made up of elements known as noble gases. Besides krypton, these elements are: helium, neon, argon, xenon, and radon. All noble gases were characterized relatively late compared to other elements. They all conduct electricity, fluoresce, and are odorless and colorless. Besides that, they have very low chemical reactivity. Because of their stability, they are often used to maintain a safe, constant environment. As krypton shares all of these characteristics, it was difficult for chemists to find it. That's why it was most likely given that name.
The above statement is common in the parlance of Computer Vision and Pattern Recognition.
<h3>
What is Pose?</h3>
Pose to pose is a term used in animation to describe the process of creating key poses for characters and then inbetweening them in intermediate frames to give the illusion that the character is moving from one pose to the next.
The goal of Agnostic Pose Estimation is to develop a pose estimation model that can detect the pose of any class of object using only a few samples with keypoint definition.

Answer:
The correct answer is to compare.
For a reader to compare two or more things, the reader must consider how things are different.
Another option for the sentence could be to contrast. Compare or contrast are equally right,
A good reader needs to understand the different concepts contained in a text. If the reader does not understand the differences it would be difficult for it to have a clear idea and reach a valid conclusion. So, in order to do this, the reader has to compare ideas, propositions, theories or any other element that helps him recognize the differences.
The statements that are true for the aviation combat element of a MAGTF are:
- The aviation combat element is usually composed of an aviation unit headquarters and various other aviation units or their detachments.
- It can vary in size from a small aviation detachment of specifically required aircraft to one or more Marine aircraft wings.
<h3>What is Aviation?</h3>
This refers to the movement of goods, people, and weapons from one location to another, through aircraft.
Hence, we can see that based on the given description of the functions of the MAGTF, we can see that they are in overall control of the aviation combat elements and they have a unit headquarters and detachments.
