WARNING=Never ever try this at home. This reaction should be done in minute quantities, and outside the home.
When the orange poisonous compound Mercury(II) Oxide is heated, it produces poisonous vapours of Mercury (which become liquid after reaching the room temperature) and Oxygen. Here is the balanced equation for this=
2 HgO ---Δ---> 2 Hg + O2
This compound is the chromium phosphate.
They both have the word COMPOUND :)
Chlorine oxide would be a covalent compound, and not an ionic compound.

Mercuryfluoride
The formula given is for mercury (I) fluoride, also known as mercurous fluoride.
HgF
That would be Mercury(II) fluoride. Idiot.
The empirical formula for Hg₂F₂ is HgF. This is because the empirical formula represents the simplest whole-number ratio of atoms in a compound.
18k hgf would stand for 18k heavy gold filled ( not solid gold )
It could mean 18 karat "hollow gold filled". I'm not familiar with a manufacturer's hallmark that is "HGF".
Heavy gold filled
"14k HGF" typically refers to a type of gold jewelry or item that is made from 14 karat gold and may include the initials "HGF," which could stand for a brand, designer, or manufacturer. The "14k" indicates that the gold is 58.3% pure, with the remaining 41.7% being other metals, which is common in jewelry for durability and color. If "HGF" has a specific context or meaning beyond that, it may require additional information to clarify.
An angle whose measure is 20 degrees!
"HGF" or hollow gold filled jewelry is considered a fine jewelry and should be treated with the same caution when cleaning. To clean HGF jewelry a solution of Mr. clean, water, and ammonia can be used. Mix half Mr. Clean and water with a small amount of ammonia. This is safe for all types of fine jewelry and is used by many jewelry stores. Allow the jewelry piece to soak for 15 seconds in this solution then rinse with water and dry.
Then p/q is a rational number.
