Explanation:
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.

Using the image attached. The option that shows the marginal rate of substitution is option b.
<h3>What is marginal rate of substitution?</h3>
The marginal rate of substitution (MRS) is known to be the number of a good that a consumer is said to be willing to take in when compared to another good, only if the new good is said to be equally satisfying.
The marginal rate of substitution (MRS) is also described as the rate in which a specific units of an item is said to be replaced by another only if by giving the same amount of satisfaction to its consumer.
Hence, The MRS concept tells about the association between the taking in of two goods or resources if consumers are said to make rational decisions.
Hence, the option that satisfy the above is option B. Therefore, Using the image attached. The option that shows the marginal rate of substitution is option b.
