First thing, you need to know what this molecule is made of.
The First atom is the Strontium Sr (For more information, used usually as a substitute of the calcium in the human body).
The Second Atom is made of 2 Fluoride F2 (because it chemical name is Strontium difluoride).
Then, you join them together and Get

And for more information, Strontium fluoride is usually used as an optical material.
Hope this Helps :)
Answer:
1.2 x 10²⁴ atoms
Explanation:
Given:
Number of moles of Ag = 2moles
Unknown is the number of atoms it contains:
Solution:
A mole of any substance is known to be made up of 6.02 x 10²³ atoms
Now;
2 moles of an atom will contain:
2 x 6.02 x 10²³ = 1.2 x 10²⁴ atoms
Answer:
The answer is dipole-dipole forces.
Explanation:
The molecule is composed of Sulfur and Oxygen, which are both elements with high electronegativities. As a result, this is a covalent bond, as they are both nonmetals. Since Sulfur has a partially positive charge, and Oxygen has a partially negative charge, it appears that the substance is polar, meaning that there are different charges within the atom. Of the answer choices, Dipole-Dipole forces are the only ones that involve polar substances, and they different charges, especially since there is no hydrogen indicating a hydrogen bond, and London forces contain nonpolar substances with an overall charge of the molecule.
