Answer:
Explanation:
A chemical bond formed when two atoms share three pairs of electrons is a <u>triple bond</u>; it is best described as <u>covalent</u>.
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
Answer:
metallic bonding
Explanation:
Metallic bonding is bonding where electrons exist as "sea of electrons" meaning they can go anywhere in the structure and are not localized in specific place like covalent bonds are sometimes.
It is possible to dehydrate neutral and basic gases, amines, low-boiling alcohols, and ethers using calcium oxide, a basic drying agent. its chemical formula is CaO.
CaO cannot be substituted with sulfuric acid. Because the salt ammonium sulfate is created when sulphuric acid and ammonia combine, this is the case. Calcium oxide is a solid that is odorless, white, gray-white, and appears as hard lumps. powerful skin, eye, and mucous membrane irritant. used in fertilizers and pesticides. The group of calcium oxides with a 1:1 ratio of calcium to oxygen includes calcium oxide. It functions as fertilizer.

Answer:
Explanation:
Using the Ideal Gas Law we have 
and the number of moles n could be expressed as 
, where m is the mass and M is the molar mass.
Now, replacing the number of moles in the equation for the ideal gass law:
If we pass the V to divide:
As the density is expressed as 
, we have:
Solving for the density:
Then we need to convert the units to the S.I.:
Finally we replace the values:
