This isotope does not occur in the environment and thus must be produced synthetically.
Yes, H2C2O4, also known as oxalic acid, is a weak acid that occurs naturally in some plants and can also be produced synthetically. It is commonly used as a reducing agent in chemical reactions and in household applications such as rust removal.
Plutonium and xenon are radioactive elements. Plutonium is a synthetic element, while xenon occurs naturally but can also be produced synthetically. Barium and cesium are not synthetic elements but can have radioactive isotopes.
Scandium is a natural resource but not a renewable one. It is found in the Earth's crust and is extracted through mining. Once it is used, it cannot be replenished at the same rate it is being consumed.
The smallest part of an element that occurs naturally is an atom. Atoms are the basic units of matter and contain protons, neutrons, and electrons.
Methane occurs when anaerobic (no air) bacteria decompose organic material. In this reaction there is no oxygen to convert carbon containing molecules to CO2 so th reaction only goes to CH4 which can still be oxidized further. Natural gas is thought ot be the result of decomposition of this typ in the distant past.
Oh, dude, Strontium occurs naturally, like it's just chilling in the Earth's crust, you know? It's not like we're out here cooking up Strontium in a lab or anything. Mother Nature's got that covered for us.
Carbon is not produced but mined because it occurs naturally. Carbon occurs naturally in three forms namely diamond, graphite and amorphous.
Yes, H2C2O4, also known as oxalic acid, is a weak acid that occurs naturally in some plants and can also be produced synthetically. It is commonly used as a reducing agent in chemical reactions and in household applications such as rust removal.
Xenon occurs naturally in trace amounts in Earth's atmosphere, where it is produced by radioactive decay. It can also be found in certain mineral springs and in trace amounts in some rocks and minerals. Additionally, xenon is produced as a byproduct of the process of nuclear fission.
Plutonium and xenon are radioactive elements. Plutonium is a synthetic element, while xenon occurs naturally but can also be produced synthetically. Barium and cesium are not synthetic elements but can have radioactive isotopes.
The production of snake skin occurs naturally. Once the skin is produced the old skin will fall of, either naturally or by rubbing against hard objects.
Samarium is never found free in nature, but, like other rare earth elements, is contained in many minerals, including monazite, bastnasite and samarskite: monazite (in which it occurs up to an extent of 2.8%) and bastnasite are also used as commercial sources. Misch metal containing about 1% of samarium has long been used, but it was not until recent years that relatively pure samarium has been isolated through ion exchange processes, solvent extraction techniques, and electrochemical deposition. The metal is often prepared by electrolysis of a molten mixture of samarium chloride with sodium chloride or calcium chloride. Samarium can also be obtained by reducing its oxide with lanthanum. wikepediahttp://www.answers.com/topic/samarium-iii-chloride
it occurs naturally
yes
it occurs naturally in grapes, bananas and tamarinds
No. Helium is an element.No, Helium is not manmade. It naturally occurs in nature. It can be artificially produced though.It is a noble gas on the Periodic Table, atomic number 2.
A mineral is a solid that occurs naturally in the Earth. A rock is a solid combination of minerals which also occurs naturally.
