Understanding the Law of Conservation of Mass
The law of conservation of mass states that in a closed system, mass can neither be created nor destroyed during a chemical reaction. This principle is fundamental in chemistry and helps explain the reactions that occur between substances.

Experimental Scenario
- Aashi followed the instructions accurately by measuring the reactants:
- **5.3 g of Sodium Carbonate**
- **6 g of Ethanoic Acid**
- The products of Aashi's reaction were:
- **2.2 g of Carbon Dioxide**
- **0.9 g of Water**
- **8.2 g of Sodium Ethanoate**

Mass Before and After Reaction
- **Total Mass of Reactants**:
- 5.3 g (Sodium Carbonate) + 6 g (Ethanoic Acid) = **11.3 g**
- **Total Mass of Products**:
- 2.2 g (Carbon Dioxide) + 0.9 g (Water) + 8.2 g (Sodium Ethanoate) = **11.3 g**

Sheena's Approach
- Sheena ignored the measurement instructions:
- This could lead to an imbalance in the total mass of reactants and products.
- If Sheena used different amounts:
- The total mass may not equal 11.3 g, potentially violating the conservation law.

Conclusion
- Aashi's careful measurement demonstrates the law of conservation of mass, where the total mass remains constant before and after the reaction.
- Sheena's disregard for measurement could lead to incorrect results, reinforcing the importance of precision in chemical experiments.
This illustrates how crucial it is to follow proper procedures in chemical reactions to ensure that the law of conservation of mass is upheld.
