Is tantalum found in a pure state?
Tantalum doesn't exist in pure state in nature.
How do you make a pure sample of helium?
A pure sample of helium can be obtained by extracting it from natural gas through a process called fractional distillation. This involves cooling the natural gas to very low temperatures, which causes the various components to condense at different points. By isolating the helium gas at the corresponding temperature, a pure sample can be obtained.
A sample thought to be pure lead occupies a volume of 15.0 mi.and has a mass of 160.0g.determine the density and is the sample pure lead?
The density of the sample is calculated by dividing the mass (160.0g) by the volume (15.0 mi^3), which results in 10.67 g/cm^3. The density of pure lead is known to be 11.34 g/cm^3, suggesting that the sample is not pure lead but likely a different material with a lower density.
What will a magnet do to tantalum?
Weakly attract it. Tantalum is paramagnetic.
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.]
Is tantalum found in a pure state?
Tantalum doesn't exist in pure state in nature.
How do you make a pure sample of fluorine?
No you cannot make a pure sample of Fluorine because it is an earth made element.

How many moles of tantalum atoms are in a sample weighing 90.45 g?
To determine the number of moles, you need to divide the weight of the sample by the molar mass of tantalum. The molar mass of tantalum is approximately 180.95 g/mol. Therefore, 90.45 g / 180.95 g/mol = 0.500 moles of tantalum atoms.
How do you make a pure sample of rhodium?

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.
A sample is composed completely of gold absolutely free of impurities Which term or terms could be used to describe this sample?
The sample could be described as pure gold or 100% pure gold.
What purpose is is served when water is used instead of a sample substance?
For example to establish a zero point for an instrument or to make a measurement on water considered as a pure sample.
How do you make a pure sample of Lawrencium?
Lawrencium is very difficult to obtain and only in quantities of some atoms.
How can you make a pure sample of sodium?
Sodium is to reactive for the average human to make. though scientists produce it every day in labs
How do you make pure samples of caclium?
The most straightforward way to make a pure sample of calcium is to electrolyze a molten calcium salt with an "inert" cathode such as platinum. Considerable care is required to prevent reaction of pure calcium with the ambient atmosphere.
What is pure sample of calcium?
A pure sample of calcium is a silver-white metal that is highly reactive and not typically found in its elemental form in nature. It is commonly found in compound form, such as calcium carbonate in rocks like limestone, or in calcium phosphate in bones and teeth.
