What else can I help you with?
Is boiling temperature a characteristic property?
Yes, boiling point is a characteristic property of matter. It is called a characteristic property because no matter how much of a pure substance you have, the boiling point should remain the same. Therefore, it is a characteristic property of pure substances.
Explain why the boiling point and the melting point can be used to help identify substances-?
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
What mixture separated by fractional distillation?
fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
What is gold's freezing point?
1063 °C(lit.) Freezing points and melting points generally can be used interchangeably. Scientific data is reported as the melting point or mp. Purity will also effect the freezing point but very useful in determining the purity of a substance.
Which property of a substance does not change when the amount of the substance changes?
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
Which method would be most useful in separating two substances with very different boiling points?
distillation
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.
What is the significance of boiling point and melting point of a substance?
Melting points and boiling points are phyical constants which means specific compounds have specific melting/boiling points. Therefore you can identify a substance if you determine the mp/bp. Also you measure the purity of a mixture using melting point tests.
Why is crude oil not very useful before you have processed it?
because there are too many substances in it, all with different boiling points
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.
What is the most useful way to determine chemical properties?
One of the most useful ways to determine chemical properties is by conducting experiments such as spectroscopy, chromatography, or titration to analyze the behavior of a chemical substance under various conditions. These methods can provide valuable information on characteristics such as reactivity, solubility, acidity, and boiling/melting points. Additionally, comparing the chemical structure and composition of a substance to known data and literature can also help in determining its properties.
