Answer:
Explanation:
The first thing to have in mind is that the Ksp (constant of solubility) gives you an idea of how much soluble a salt is. <u>If the concentration of ions of that salt exceeds the kps, the salt will precipitate</u>.
The Kps of all these salts are very small compared to the 0.1 M concentration of the anions so all of them will precipitate.
The smaller the constant, the faster the salt precipitates
Having that concept in mind, the order of precipitation from first to last would be:
You will probably need more info, but it is probably accelerating and moving from one place to the next
Answer:
C) Ionic bonds
Explanation:
The ionic bonds are the strongest bond, it occurs when a metal donates electrons and a nonmetal gain these electrons. They'll be together by electrostatic force.
Metallic bonds it the second strongest bond, it occurs between metals, which loses electrons. It's an electrostatic force, but weaker than the ionic compound because it occurs between the cation and the electron.
Covalent bonds are the weakest bond. It happens between metals and nonmetals, or nonmetals and hydrogen or between atoms of hydrogen. The force that joins the atoms depends on the polarity of the molecule. Polar molecules have dipole forces, nonpolar molecules, induced dipole forces. Also, hydrogen makes special dipole forces with nitrogen, oxygen, and fluorine, called hydrogen bond.
As the stronger is the force, as difficult it will be to break it. So, ionic bonds will demand more energy to become gas, and have high melting points.
