Is helium in a balloon a pure substance not a mixture?
In theory it is a pure element. However, due the the cost of obtaining really pure helium, it is likely to contain trace amounts of other gases.
How is copper obtained from its pure form?
Copper is mainly obtained through mining of copper ores. The ore is then crushed and ground to release the copper minerals. The copper is then extracted using a process called smelting, which involves heating the ore with a reducing agent to remove the impurities and obtain pure copper metal.
Is the helium in a balloon a substance or a mixture?
Helium is an element (and therefore a pure substance) yes
How can cadmium be obtained in its pure form?
Cadmium is typically obtained in its pure form through the process of electrolysis, in which an electric current is passed through a cadmium salt solution to deposit pure cadmium on the cathode. Another method is the thermal decomposition of cadmium compounds, such as cadmium sulfide or cadmium carbonate, at high temperatures to obtain pure cadmium metal.
Are helium and gold examples of pure substances or mixtures?
They are actually elements so that is pure substances. Mixtures are more than one type of element that are in the same space but not touching. Compounds are like mixtures but they are touching.
Is helium found alone or with other elements?
In atmosphere, helium is found as a mixture along with other gases. But this helium can be isolated and obtained in pure form by suitable techniques.
Is helium used pure or is it part of a compound?
Helium is used as it is/pure. Helium is an inert gas and does not form part of compounds.
Can helium be a pure form?
Helium found in atmosphere will have other gases as impurities. But it can be isolated by suitable method (generally by adsorption of gases) to get pure helium.
Is helium used in its pure form?
Well, probably...
How can gold be obtained in a pure form?
buy gold bullion check if it 99.99% pure that is as pure as it gets
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.
Can helium be found it its pure elemental form?
Yes. helium is found in its elemental form. it is chemically inert as it has completely filled orbitals.
How is the element obtained in its pure form?
elements are obtained in its pure form by the process of distillation or fractional distillation. In this process the elements are purified using their boiling points,after this the metal are purified in the factories.
Is helium gas a pure substance or mixture?
Helium is pure as it is on the periodic table.
Is helium is pure or mixture?
Helium is a pure substance
Is helium a mixture or a pure substance?
Yes, it is a pure substance but can be mixed with other gases.
Is helium gas mixture or pure substances?
Helium gas is a pure substance
