Answer

Answer:

A. Oxygen is represented as a molecule and therefore has a subscript of 2 in the chemical equation.

Brief Explanations:

El oxígeno en la naturaleza se presenta como molécula $O_2$. En una reacción química de oxidación de magnesio ($Mg$) con oxígeno, el oxígeno se escribe como $O_2$ debido a su naturaleza molecular, mientras que el magnesio es un metal y se representa como átomos individuales en la reacción. La formación de óxido de magnesio ($MgO$) sigue la ley de conservación de la masa y la representación correcta de los reactantes y productos.
