It seems that you have missed the given options for this question which are the following: <span>A. glacial striations B. terminal moraines C. eskers D. cirques
Anyway, the correct answer would be option B. The one that are formed as glaciers retreat and leave debris behind in mounds at the front of their farthest advance are terminal moraines. Hope this answer helps.</span>
Answer:
It is a physical change.
Explanation:
While it is a chemical reaction because the salt gets dissolved, if you were to boil the water off of a salt solution, all that would be left is salt. This can be done physically. Thus, it is a physical change.
It would protect best against C) Alpha radiation, as Beta radiation is stopped by lighter metals such as aluminium, and Gamma radiation can only be stopped by heavier metals such as lead.
Except catalyst because catalyst typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
