Methane is a compound.
The answer to your question of, Is methane gas an element, a compound, homogeneous mixture, or heterogeneous mixture can be deduced as follows:
What is the structure of methane gas? CH4
Elements are a single type of atom. Anything from the periodic chart, such as H, C, Na, P, K, etc. It
can include more than one atom such as H2, but it is the same element.
In CH4, we have two elements a carbon atom (C) and 4 hydrogen atoms (H4), not one single type of atom. Therefore, it is not an element.
Compounds are two or more elements bonded together such as CO2 ( a carbon atom and 4 oxygen atoms), NaCl (a sodium atom and a chloride atom, H2O (2 hydrogen atoms and an oxygen atom).
In CH4, we have two elements a carbon atom (C) and 4 hydrogen atoms (H4), not one single type of atom. Therefore, it is a compound.
Mixtures are a combination of elements and/or compounds combined. CH4 is a compound, but we have not added another element or compound to it, so it is not a mixture. If we added an alcohol (-OH) to CH4, we could make methanol, a mixture of methane and alcohol. Therefore, methane is not a mixture.
no, it's a pure substance. it's a compound
Methane is not a mixture. It is a pure substance.
Neither.
Methane is not a mixture but a pure substance.
No. Helium gas, He(g), is a pure element.
Yes
Compound
Methane is a compound. It is made of hydrogen, and carbon. Chemical formula of it is CH4.
Homogeneous and heterogeneous reactions are important in catalysis and oxidation coupling of methane over chloride.
Methane (CH4) is a compound because it is composed of at least two atoms of a different element.
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
Methane is a chemical compound (CH4), not a chemical element; methane is important as fuel or as feedstock for the chemical industry.
Methane is a chemical compound - CH4.
it's a compound
Methane is a compound. It is made of hydrogen, and carbon. Chemical formula of it is CH4.
Homogeneous and heterogeneous reactions are important in catalysis and oxidation coupling of methane over chloride.
Methane is not an element. It is a compound of two elements: carbon and hydrogen.
Compound - Hydrocarbon (alkane - single carbon to carbon bonds)
Methane (CH4) is a compound because it is composed of at least two atoms of a different element.
Methane is a chemical compound made of the elements Carbon and Hydrogen. Writtan as CH4.
Ch4 is not an element, it's the compound Methane
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
Nope... it's a compound.
