3CO₂ is a chemical formula, not a symbol. It represents three molecules of carbon dioxide, where "CO₂" indicates one molecule of carbon dioxide composed of one carbon atom and two oxygen atoms. The "3" in front signifies that there are three such molecules present.
In the chemical formula 3Co2, the "3" represents the number of moles or units of the compound Co2. This means there are three units of cobalt (Co) combined in the formula, indicating a total of six cobalt atoms (since each Co2 contains two cobalt atoms). The subscript "2" indicates that each unit of Co2 consists of two cobalt atoms.
With the symbol of a chemical element - of course, if you think to a chemical formula.
Formula= ClO-
No, the chemical equation is not balanced. It should be: 2Fe2O3 + 3C -> 4Fe + 3CO2.
2 C7H5N3O6 → 3 N2 + 5 H2O + 7 CO + 7 C it is considered a decomposition reaction http://en.wikipedia.org/wiki/Trinitrotoluene
Coefficients :)
C3h8 + 5o2 -----> 3co2 + 4h2o
Born does not have a formula but a symbol as it is an element. its symbol is B.
