To evaluate the experiment, we can start by determining the initial masses of the reactants and then analyze the outcome.
-
Initial Masses:
- Manganese (Mn): 7.85 grams
- Oxygen (O): 2.29 grams
Total mass of reactants = Mass of Mn + Mass of O = 7.85 g + 2.29 g = 10.14 grams
-
Mass of the Product:
- The mass of the powdered product formed in the reaction is 10.14 grams.
-
Analysis: According to the law of conservation of mass, the total mass of the reactants should equal the total mass of the products. In this case:
- Total mass of reactants = 10.14 grams
- Total mass of product = 10.14 grams
Since the total mass of the reactants (10.14 g) matches the mass of the product formed (10.14 g), this suggests that the reaction was successful and that no mass was lost in the process.
- Conclusion: The reaction between manganese and oxygen produced a powder that corresponds perfectly with the initial mass of the reactants, indicating an efficient and complete reaction with no loss of mass. If you need any further calculations, such as the stoichiometry of the reaction or identification of the product formed, please provide the chemical reaction details or the desired analysis.
