I'll not give you a whole answer - as this is obviously a homework question !... However - a compound - is the joining of two or more elements to form one molecule. For example - common table salt is a compound of sodium and chlorine. The chemical name for salt is Sodium Chloride. Pure air, however is composed of individual elements (oxygen, nitrogen, hydrogen, argon, carbon and other 'trace' elements) which are 'free-flowing' - in that the individual atoms are not combined into a single atom of air.

What is the melting point of iron bromide?
Iron bromide does not have a distinct melting point since it is typically found as a mixture of different iron bromide compounds. The melting point can vary based on the specific compound in the mixture.
What is the melting point of the mixture?
The melting point of a mixture is the temperature at which the solid components of the mixture turn into a liquid.
Is antifreeze element or compound or mixture?
Antifreeze is typically a compound. It often contains ethylene glycol or propylene glycol, along with other additives to help lower the freezing point of the liquid in a car's cooling system.
What is the melting point of boron in cluis?
The melting point of boron is around 2076°C in a vacuum environment. However, in a chloride (Cluis) environment, the melting point may vary depending on the specific compound or mixture being considered.
How can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
How melting and boiling point decide that it is a mixture or compound?
i really dont know
How is the melting of an impure compound expected to change with recrystallization?
During recrystallization, impurities are removed as the compound is dissolved and then slowly cooled to allow for the formation of pure crystals. As a result, the melting point of the compound should increase after recrystallization because the presence of impurities lowers the melting point of the compound.
What is table salt mixture compound or solution?
You did not mention a mixture of 'what' and table salt. On the chance that you meant, "Water", then the compound called, "salt" is in solution with water up to the saturation point. After that, any added salt will simply fall to the bottom of the container, and not go into solution.
What is the melting point of iron bromide?
Iron bromide does not have a distinct melting point since it is typically found as a mixture of different iron bromide compounds. The melting point can vary based on the specific compound in the mixture.
What is the melting point of the mixture?

The melting point of boron is around 2076°C in a vacuum environment. However, in a chloride (Cluis) environment, the melting point may vary depending on the specific compound or mixture being considered.
Is ether a basic compound?
Ether is indeed a pure substance rather than a mixture. The boiling point of ether is 94.28 degrees Fahrenheit or 34.6 degrees Celsius.
How can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
What gas condense first?
When cooling down (and/or compressing) a gas mixture, the first condensing gas has the highest boiling (= condensation) point temperature, in other words the least volatile compound.
Does a compound have a fixed melting point?
If a substance is a compound, you know exactly what is in it. Scientists say that compounds have a fixed composition. that means that they are always made up from the same atoms, present in the same ratio.
