Respuesta :
The oxygen in the final equation appears as reactant Upper O subscript 2 (g). Thus, option A is correct.
The chemical equations are the representation of the chemical formula involved in the equation as the reactant and the formed product.
What will be the form of oxygen?
The given chemical equations are:
- [tex]\rm C\;(s)\;+\;\frac{1}{2}\;O_2\;(g)\rightarrow\;CO\;(g)[/tex]
- [tex]\rm CO\;(g)+\;\frac{1}{2}\;O_2\;(g)\rightarrow\;CO_2\;(g)[/tex]
The final chemical equation formed for the formation of Carbon dioxide is the sum of the two equations.
The final equation is achieved by substituting equation 1 in equation 2.
[tex]\rm C\;(s)\;+\;\frac{1}{2}\;O_2\;(g)\;+\;\dfrac{1}{2}\;O_2\;(g)\;\rightarrow\;CO_2\;(g)\\\\ C\;(s)\;+\;O_2\;(g)\;\rightarrow\;CO_2\;(g)[/tex]
The oxygen in the final equation appears as reactant Upper O subscript 2 (g). Thus, option A is correct.
