Final answer:
To calculate the mass of the products, the initial mass of reactants is needed as per the law of conservation of mass. Without the initial mass of Magnesium oxide (MgO), it is impossible to find the mass of Magnesium (Mg) and Oxygen (O2) produced, thus the information given is insufficient.
Step-by-step explanation:
The mass of products in a chemical reaction can be determined by using the law of conservation of mass, which states that in a closed system, matter is neither created nor destroyed, but it can change forms. This means that the mass of the reactants will equal the mass of the products.
For the reaction 2MgO → 2Mg + O2, we would need to know the initial mass of Magnesium oxide (MgO) to determine the mass of the products. However, since the initial mass of MgO is not provided in the problem, there isn't enough information to calculate the mass of the Magnesium (Mg) and Oxygen (O2) produced.
Therefore, the correct answer to the student's question is: d. There is not enough information given to answer the question.
