Can you predict boiling point of a compound with the help of boiling points of elements in it?
The intra and inter molecular forces will help to determine the higher boiling.
Intra molecular forces are Polar/Non-polar covalent bonds and ionic bonds. Covalent bonds are stronger than ionic bonds.
Polar covalent bonds will have a higher boiling point because non-polar covalent bonds are only affected by London forces.
Intermolecular forces are hydrogen bonding, diapole-diapole and London. All molecules have London forces.
Also the higher the electro-negativity the higher the boiling point.
If all of the intra and inter molecular forces are the same, refer to the electro-negativity and size. The greater the electro-negativity and size, the higher the boiling point.

Are elements in a compound heated until they boil?
No, elements in a compound are not necessarily heated until they boil. Boiling point is the temperature at which a substance changes from a liquid to a gas. Heating a compound can be used to separate its components by taking advantage of differences in boiling points through techniques such as distillation or chromatography.
How can one determine the boiling points of compounds?
The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
How can you determine whether a compound is ionic or molecular?
You can determine whether a compound is ionic or molecular based on the types of elements it contains. Ionic compounds typically consist of a metal and a nonmetal, while molecular compounds are made up of nonmetals only. Additionally, ionic compounds tend to have high melting and boiling points, while molecular compounds have lower melting and boiling points.
How to find the boiling point of a compound"?
To find the boiling point of a compound, you can consult a reference book or online database that lists the boiling points of various compounds. Alternatively, you can use a laboratory technique called distillation to determine the boiling point experimentally.
What elements have the lowest boiling and melting points?
The noble gases, such as helium and neon, have the lowest boiling and melting points among the elements. These elements are gases at room temperature and have very weak interatomic forces that require little energy to separate them into individual atoms.
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Are elements in a compound heated until they boil?
No, elements in a compound are not necessarily heated until they boil. Boiling point is the temperature at which a substance changes from a liquid to a gas. Heating a compound can be used to separate its components by taking advantage of differences in boiling points through techniques such as distillation or chromatography.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Why elements of the same shape have different boiling points?
elements of same shape have different boiling points because their bonding may vary! the elements with covalent bonds will have high boiling point!
Elements in the compound are heated until they what?
Elements in a compound are heated until they reach their melting or boiling points, depending on the desired outcome. Heating a compound can break chemical bonds, allowing the elements to separate from each other in the form of gases, liquids, or solids.
When zinc metal is mined the rock that contains zinc is dissolved in acid to form a compound Predict what kind of methods could be used to separate the compound?
One method to separate the compound could be electrolysis, where an electric current is passed through the compound to split it into its individual elements. Another method could be fractional distillation, which takes advantage of the different boiling points of the elements in the compound to separate them. Additionally, chemical precipitation could be used to selectively isolate one element from the compound by adding a reagent that forms a precipitate with one of the elements.
Which Hg compounds have boiling points exceeding 1100C?
No mercury compound has a boiling point as high as this.
Describe a method for separating a compound into its constituent elements?
One method for separating a compound into its constituent elements is through chemical decomposition, such as heating the compound to break its chemical bonds. Another method is through electrolysis, where an electric current breaks down the compound into its elements at the electrodes. Additionally, fractional distillation can be used to separate a mixture of compounds based on their different boiling points.
Where elements on the periodic table with the highest boiling points app?
Elements with the highest boiling points are typically found in the group of transition metals and some metalloids. For example, tungsten (W) has one of the highest boiling points at around 5,555°C. These elements often have strong metallic bonds and a dense atomic structure, which contribute to their elevated boiling points. Additionally, some heavy noble gases like radon also exhibit high boiling points, but generally, the trend is seen among the transition metals.
What elements have high boiling points?
As examples are wolfram, tantalum, rhenium.
Why use vacuum distillation on compounds with high boiling points?
Vacuum distillation lowers the boiling point of the compound by reducing the pressure in the system, which helps prevent thermal degradation or decomposition of the compound at high temperatures. This is especially useful for compounds with high boiling points that may decompose or react at their normal boiling points.
Predict the order of increasing boiling points of the noble gases?
The boiling points of noble gases increase with increasing atomic number. Therefore, the order of increasing boiling points is helium < neon < argon < krypton < xenon < radon.
