Four oxygen atoms
"CO2" stands for carbon dioxide, which is a chemical compound made up of one carbon atom bonded to two oxygen atoms. The "2" in "2CO2" indicates that there are two molecules of carbon dioxide present.
Carbon monoxide (CO) is a diatomic molecule composed of one carbon atom and one oxygen atom, so it has a total of two elements.
There are three elements in CO2: one carbon atom and two oxygen atoms.
No, for all elements the smallest particle that can exist independently is an atom.
Elements.
One.
"CO2" stands for carbon dioxide, which is a chemical compound made up of one carbon atom bonded to two oxygen atoms. The "2" in "2CO2" indicates that there are two molecules of carbon dioxide present.
there are two elements, hydrogen and oxygen and one atom of each
Carbon monoxide (CO) is a diatomic molecule composed of one carbon atom and one oxygen atom, so it has a total of two elements.
It says that in your molecule, the element in front of the little 2 occur twice. So in CO2, a carbon-atom occurs once, and the oxygen-atom occurs twice.
There is 1 atom in hydrogen and 1 atom in chlorine.
The half reaction for the given chemical equation 2CO + O2 -> 2CO2 is: 2CO -> 2CO2 (in acidic medium) 2CO -> 2CO2 + 2H2O + 2e- (in basic medium)
Carbon monoxide is a molecule consisting of two elements: carbon and oxygen.
There is one element only. Oxygen atom is there.
You mean elements? So far scientists have brought out some 109 elements. If you mean atom model, then first Prout's model Then Thomson's, Rutherford's, Bohr's, Sommerfeld's. Finally vector atom model.
Two elements, two hydrogen atoms and one oxygen atom
There are three elements in CO2: one carbon atom and two oxygen atoms.
