Answer:
On google it says this: HF will be the most soluble in water. Substances which form hydrogen bonding with polar water molecules are soluble in water. F has the highest electronegativity amongst other halogens.
Idk maybe A?
Explanation:
Answer: -
Oxidation, Oxygen
Explanation: -
Burning of magnesium gives us magnesium oxide.
The chemical symbol of magnesium is Mg.
The chemical symbol of magnesium oxide is MgO.
So, the balanced chemical equation is
2Mg + O2 – 2 MgO.
We see that the element added is O Oxygen.
So, the reaction is oxidation.
In oxidation always, oxygen is the common element involved in all chemical reactions of this kind.
Neon is a member of the noble gas family. Other elements in this family includes helium, argon, krypton, xenon, and radon. These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.
