Answer:
a. ½O2
b. O2
c. 3O2
d. 6O2
Explanation:
Hello!
In this case, since balancing chemical reactions can be attained by adding coefficients prior to each species in the chemical equation, we infer that the following representations are correct because they have a coefficient and the molecule O2 as diatomic oxygen:
a. ½O2
b. O2
c. 3O2
d. 6O2
It means that e. and f. are wrong because even when they have the coefficient, the molecule O2 is not properly written.
Best regards!
The correct representations of O2 and its coefficient are: ½O2, O2, 3O2, 6O2.
Oxygen molecule O2 exists as a diatomic molecule that comprises two atoms chemically bonded together.
When oxygen undergoes a chemical reaction with other compounds, the diatomicity of oxygen O2 is still usually maintained.
The coefficient of oxygen O2 varies depending on the reaction in which oxygen undergoes such as:
An oxygen molecule does not exist as 3O and 5O3 represent a reaction of ozone.
Therefore, we can conclude that the correct representations of O2 and its coefficient are: ½O2, O2, 3O2, 6O2.
