Answer:
A crystalline solid
Explanation:
Most solids form with a regular arrangement of their particles because the overall attractive interactions between particles are maximized, and the total intermolecular energy is minimized, when the particles pack in the most efficient manner. The regular arrangement at an atomic level is often reflected at a macroscopic level. Liquids dont use to have this kind of arrangements or shapes.
Cześć, nie mówię po polsku, więc zrobiłem to w Tłumaczu Google, więc przepraszam, jeśli coś brzmi śmiesznie.
chlor (VII) i tlen - ten wzór to 
, a tlenek chloru jest bezwodnikiem kwasu nadchlorowego.
węgiel i wodór - wzór na węgiel i wodór to CnH2n + 2), jest to związek organiczny, a niższa klasyfikacja jest taka, że jest to również węglowodór aromatyczny.
Mam nadzieję, że to pomoże, błogosławionego i cudownego dnia! :-)

Answer:
The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water. What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea.

Answer:
Incomplete question: A student prepares a 0.54 mM aqueous solution of butanoic acid...
The answer is: The percentage of dissociation is 15.4%
Explanation:
Given:
Ka = 1.51x10⁻⁵
Concentration = 0.54 mM = 0.54x10⁻³M
The reaction is:
C₄H₈O₂ = C₄H₇O₂⁻ + H⁺
I 0.54x10⁻³ 0 0
E 0.54x10⁻³(1-x) 0.54x10⁻³x 0.54x10⁻³x
Where x is the degree of dissociation
![Ka=\frac{[H^{+}][C_{4}H_{7}O_{2}^{-} }{[C_{4}H_{8}O_{2} } \\1.51x10^{-5} =\frac{0.54x10^{-3}x^{2} }{1-x} \\x^{2} +0.028x-0.028=0\\x_{1} =0.154\\x_{2} =-0.182](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%5BC_%7B4%7DH_%7B7%7DO_%7B2%7D%5E%7B-%7D%20%20%20%20%20%7D%7B%5BC_%7B4%7DH_%7B8%7DO_%7B2%7D%20%20%20%7D%20%5C%5C1.51x10%5E%7B-5%7D%20%3D%5Cfrac%7B0.54x10%5E%7B-3%7Dx%5E%7B2%7D%20%20%7D%7B1-x%7D%20%5C%5Cx%5E%7B2%7D%20%2B0.028x-0.028%3D0%5C%5Cx_%7B1%7D%20%3D0.154%5C%5Cx_%7B2%7D%20%3D-0.182)
We will choose the positive value
x = 0.154
The percentage of dissociation is 15.4%
Molecules are pure substances. This is because a molecule has a set ratio of elements in order to make that compound have the same properties.
For example:
Water is H₂O. Always. There is no alternate water formula.
Sand however, is a mixture, who knows exactly what is in sand, and how much of it is in there.
