What is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
How can you get a pure sample of germanium?
Pure germanium is obtained by distllation of germanium tetrachloride, followed by hydrolysis of GeCl4 to GeO2 and reducing of GeO2 with hydrogen to Ge.
Why did Antoine lavoisier collect hydrogen chloride gas by displacement of mercury?
Antoine Lavoisier collected hydrogen chloride gas by displacement of mercury in order to obtain a pure sample of the gas for further study and analysis. The method allowed him to separate and collect the gas without it reacting with the atmosphere or other components present in the reaction.
How do you make pure samples of nickel?
One approach would be to reduce nickel oxide in a hydrogen stream.Alternatively, one could oxidize NiS on an oxygen stream to get rid of the volatile sulfur.An alternative approach would be to electrowin the metal from an acid solution, i.e. by electroplating.If you required very high purity Ni, then zone refiningof a cylindrical sample will produce very pure metal.[For example, high purity Tantalum, 99.999%, may be produced by this method.]
How do you make pure samples of selenium?
One common method to obtain pure samples of selenium is through the process of sublimation. Selenium can be heated to a temperature where it vaporizes and then allowed to condense back into a solid state in a clean container, resulting in a relatively pure sample. Further purification techniques such as recrystallization or distillation may also be employed to increase the purity of the sample.
How do you make a pure sample of Iodine?
To make a pure sample of iodine, you can start with a mixture containing iodine and other substances, then use a process like sublimation to separate the iodine from the other components. Sublimation involves heating the mixture to allow the iodine to vaporize and then cooling it to condense the iodine back into solid form. This process helps to obtain a pure sample of iodine.
Which methods is used to obtain pure copper sulphate from impure sample and how?
One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
How would you prepare a sample of pure dry ammonium nitrate?
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.
How do you make a pure sample of Lawrencium?
Lawrencium is very difficult to obtain and only in quantities of some atoms.
What is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
What type of intermolecular forces would you expect to find in a pure liquid sample of carbon tetrachloride?
In a pure liquid sample of carbon tetrachloride (CCl4), you would expect to find London dispersion forces. Carbon tetrachloride is a nonpolar molecule, so it does not have dipole-dipole or hydrogen bonding interactions.
How do you prepare a pure sample of dry carbonate using solution of ammonium carbonate?
To prepare a pure sample of dry carbonate using a solution of ammonium carbonate, you would need to first evaporate the solution to dryness to obtain solid ammonium carbonate. Then, heat the solid in a crucible to decompose it into ammonia, carbon dioxide, and water. Finally, collect the carbon dioxide gas and purify it to obtain the pure dry carbonate.
How can you get a pure sample of germanium?
Pure germanium is obtained by distllation of germanium tetrachloride, followed by hydrolysis of GeCl4 to GeO2 and reducing of GeO2 with hydrogen to Ge.
How could you determine if a sample gold is pure?
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
How could you determine is a sample of gold is pure?
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
Is a sample of pure solid chromium is homogeneous?
Yes, a sample of pure solid chromium would be considered homogeneous because it consists of a single element (chromium) uniformly distributed throughout the sample. This means that there would be a consistent composition and properties throughout the material, making it homogeneous.
Can hydrogen be used in it's pure state?
The answer would be no. In Earth there is no hydrogen source in its pure form. It is only found in compound with other elements.
