The symbol for the hydroxide ion is _____.
H
H3O-
H(OH)
OH-
Answers
Answer : The symbol of hydroxide ion is .
Explanation :
Hydroxide ion is a negatively charged molecule which are made up of one oxygen molecule bonded to one hydrogen molecule.
Hydroxide ion is formed by the loss of proton from the water molecule.
The hydroxide ion is represented as .
OH⁻ is the chemical formula or symbol for hydroxide. Therefore, the correct option is option D among all the given option.
A chemical formula is a way to describe the chemical ratios of the atoms that make up a specific chemical compound or molecule in chemistry. Chemical element numbers, symbols, and on occasion other symbols, including parentheses, dashes, brackets, commas, and plus (+) and minus () signs, are used to represent the chemical elements. Which may also include subscripts or superscripts. Since a chemical formula inherently wordless, it cannot be considered a chemical name. A chemical formula does not equal a complete chemical structural formula, despite the fact that it may suggest certain basic chemical structures. Hydroxide is represented as OH⁻.

because the fiber is a natural fiber
because the fiber has long range order
because the fiber has a refractive index greater than 1.52
because the refractive index is less than 1.52
Answers
Answer:
Because of the chemical makeup of the fiber.
Explanation:
The birefringence is the difference between the refractive index of a fiber in a direction at parallel to the fiber axis and in a direction at right angles. It is caused by asymmetric core shape for the two axes, and majorly one of the manufacturing imperfections. It helps in controlling polarization property inside the fiber.
Inevitable manufacturing imperfections in optical fiber leads to birefringence, which is one cause of pulse broadening in fiber-optic communications. Such imperfections can be geometrical (lack of circular symmetry), due to stress applied to the optical fiber and/or due to bending of the fiber.
Answers
Answer: Option (1) is the correct answer.
Explanation:
Compounds in which atoms transfer electrons result in the formation of ionic bond. Whereas when atoms in a compound share electrons then they result in the formation of covalent compounds.
Also, it is known that like dissolves like. Hence, water being an ionic compound itself dissolves other ionic compounds.
Thus, out of the given options HCl is a covalent compound, therefore, HCl is the compound that becomes less soluble in water as the temperature of the solution is increased.

C.
They are the most expensive materials on earth.
D.
They break down easily.
Answers
elements are the make up of matter
it is not the smallest particle of a material,also not all elements are expensive
some can be found easily and also elements are simple without combination of other substances so it might be able to be splitted
I think the best answer among the choices listed above is option A. Elements are the smallest particles of any material. It cannot be broken down into more tiny particles. There are 118 known elements where 94 occurs naturally and the 24 remaining are synthetic.

Explanation:
Cyclic hydrocarbons are organic compounds that consist of carbon and hydrogen atoms that bond to form rings or cyclic structures. The simplest are cycloalkanes, hydrocarbons formed by a closed carbon chain with all the simple bonds.
There is a very special group of cyclic hydrocarbons called aromatic hydrocarbons. Its name is due to the fact that the first to be discovered had pleasant smells. They all start from a basic structure that can be repeated many times. An example of this type of hydrocarbon is bancene.
