Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take ![[SiO_4]^4^-](https://tex.z-dn.net/?f=%5BSiO_4%5D%5E4%5E-)
as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.
Liquefied Natural Gas
Explanation:
Gases are usually liquefied in the downstream sector during crude processing. These natural gases are products of distillation of crude oil in fractionating columns. Some of them are also found in geological formations.
- To easily transport these gases, they are liquefied in vessels that carries them from one place to another.
- Liquefaction is the process of converting a gas or solid into a liquid form.
- Gases are usually compressed under very high pressure into vessels through which can make them easier to transport.
- Gases do not have a fixed volume and they typically assume the volume of any container they are taken into.

Answer:
A. True
Explanation:
The octane number is determined by comparing the characteristics of gasoline to isooctane (2,2,4-trimethylpentane) and heptane. The correct option is option A.
Basically, the higher the octane number, the greater the resistance of the gasoline to knocking.
Answer: covalent bond
Explanation: Yeah that's the answer
The answer is because like electric charges do not attract with each other. Ions either lack or have excess electrons in their atomic structure. Ions with a positive charge are called cations. They lack electrons in their atoms so they have to pair up with negatively charged ions, called anions, because they have excess electrons. Together, they form a compound that is neutral.
