because the arrangement of molecules are different in both.
Melting points are routinely used to determine the purity of a substance. Impurities often lower the melting point of a substance, so a lower-than-expected melting point can indicate the presence of impurities. Melting points are also used to identify unknown substances by comparing their melting points to established values.
Metalloids typically have higher melting points than non-metal elements but lower melting points than most metals. This is because metalloids have properties that are intermediate between metals and non-metals, giving them melting points that fall between the two categories.
If the two solids have the same texture and color but different solubilities in water, it suggests they are two different substances with distinct chemical properties. The varying solubilities indicate differences in their chemical structures and interactions with water molecules. Further analysis such as melting points, chemical reactions, or spectroscopic techniques may help identify the substances.
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
freeze one liquid while the other one is still liquidized.

- melting point is a specific characteristic of a substance; consequently we can distinguish these substances knowing the melting point - the knowledge of the melting point is absolutely necessary to design technological processes, to made alloy, to use surely materials at high temperature, etc.
Low melting and boiling points. Some are polar and some are nonpolar. Those that are polar will dissolve in water. They also do not conduct electricity.
It depends on which two ions are bonded ionically. But normally most ionic bonds' melting points are really high - sometimes even reaching 3000 degrees Celsius or more. It is similar to those of the metals.
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
- a substance can be identified after the melting point because it is a specific physical characteristic- melting points knowledge is necessary for technology
An ionic compound has an ionic bond (held together by two oppositely charged ions) and is between a metal and a non metal. A molecular compound has covalent bonds , which is when atoms are bound by the sharing of electrons.
A covalent compound is a chemical compound formed by the sharing of electron pairs between atoms. These compounds typically have lower melting and boiling points compared to ionic compounds, and they are commonly found in organic compounds. They are also known as molecular compounds.
Galium n Mercury
They have low melting and boiling points which increases down the group. They form diatomic molecules They form simple ions with -1 charge They react with hydrogen to form acidic compound
in column two
Metalloids typically have higher melting points than non-metal elements but lower melting points than most metals. This is because metalloids have properties that are intermediate between metals and non-metals, giving them melting points that fall between the two categories.
