For what two reasons are the melting points routinely used?

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.


Do metalloids have a higher melting point then metals?

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.


What can you conclude if you have two unidentified solids of the same texture and color that have different solubilities in 100 grams of water at 20 degrees C?

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.


Explain why the boiling point and the melting point can be used to help identify 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.


How could you use a difference in melting points (freezing points) to separate a solution of two liquids?

freeze one liquid while the other one is still liquidized.

For what two purposes are melting points routinely used?

- 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.


What are the two properties of a compound?

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.


Ionic bond melting point?

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.


Effect of impurities on melting point and melting point?

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.


What two uses do chemist put the melting points of substances?

- a substance can be identified after the melting point because it is a specific physical characteristic- melting points knowledge is necessary for technology


How are an ionic compound and a molecular covalent compound different?

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.


What is a covalent compound-?

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.


Generally melting points of metals are high name two metals whose melting points are so low that they would melteven when kept in hand?

Galium n Mercury


What are two prperties of the halogens?

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


Where on the periodic table are the melting point and boiling points the highest?

in column two
