The answer is oxygen. Oxygen is an element and its most common form is as O2 , another form or "allotrope" is ozone, O3.
The others are compounds because they contain two or more different elements,
water, H2O
methane, CH4
Carbon dioxide, CO2
Carbon dioxide is chemical compound. Oxygen and nitrogen are chemical elements.
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
For example methane gas; after burning carbon dioxide and water are released.
In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
Carbon dioxide is a compound consisting of carbon and oxygen.
No. Carbon dioxide is a chemical compound of carbon and oxygen.
Carbon dioxide is chemical compound. Oxygen and nitrogen are chemical elements.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
Carbon dioxide is a compound of carbon and oxygen.
Carbon dioxide is a compound of carbon and oxygen.
Carbon dioxide is a compound of carbon and oxygen.
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
carbon dioxide
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
No, Carbon dioxide is one compound and oxygen is another.
It is a compound of 2 elements, oxygen and carbon.
