Answer is: a bottle of acetic acid contains a solid.
Acetic or ethanoic acid (CH₃COOH) when undiluted is called glacial acetic acid.
Glacial acetic acid has freezing point (melting point) around 16.6°C, so it will be at solit state.
Vinegar is mixture of acetic acid (CH₃COOH) and water (H₂O). Vinegar is colourless liquid with sour taste and pungent smell, freezing point of the vinegar is lower than glacial acetic acid.
Acetic acid dissociate in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻).
Balanced chemical reaction (dissociation):
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
Explanation:
Law of conservation of matter/mass
the law of conservation of mass states that matter cannot be created nor destroyed but can be changed from one form to another.
by Antoine Lavoisier
Law of multiple proportions
the law of multiple proportions states that if two elements, A and B combine to form more than one chemical compound, the various masses of element A, which combine separately with a fixed mass of the other element B are in simple multiple ratios.
by chemist John Dalton
Law of reciprocal proportion
the law of reciprocal proportion states that the masses of several elements A, B, C
which combine separately with a fixed mass of another element D are the same as or simple multiples of, the masses in which A, B, and C themselves combine.
by Jeremias Richter
Law of definite proportions
the law of definite proportions states that all pure samples of a particular chemical combined contain similar elements combined in the same proportion by mass.

Hi, There! your Answers are Below And Are 100% Correct
Symbols are the basis of culture. A symbol is an object, word, or action that stands for something else with no natural relationship that is culturally defined

(Dont forget to mark thanks)
Answer:
Wavelength
a. Increases as energy decreases
b. Often measured in units such as nanometers (nm)
f. A measure of distance
Frequency
c. Often measured in units such as Hertz (Hz)
d. Increases as energy increases
e. A measure of cycles per unit time
Explanation:
Wavelength increases when the energy decreases whereas frequency increases as energy increases. Wavelength is measured in nanometers (nm) whereas frequency is measured in hertz. Frequency refers to the number of cycles in a unit of time while on the other hand, the distance between successive crests of a wave, especially in a sound wave or electromagnetic wave is known as wavelength.
Explanation:
A number can be written in the form of scientific notation as follows :
x is any real number and y is integer
(a) The distance between Pluto and the Sun is 5,913,000 km.
There are 6 digits after 5. In scientific form is given by :
(b) The density of nitrogen gas is 0.0012506 g/cm³.
There are 2 digits before 1. In scientific notation,
