Explanation:
Law of Conservation of Mass states that matter can neither be created nor destroyed, it can only be transformed from one form to another. This means that the total mass of reactants in a chemical reaction must be equal to the total mass of products formed.
Given that Aashi and Sheena were asked to take 5.3 g of sodium carbonate and 6 g of ethanoic acid to make 2.2 g of carbon dioxide, 0.9 g of water and 8.2 g of sodium ethanoate. Aashi followed the instructions but Sheena took the chemicals without measuring their amounts.
From the given information, we can conclude that:
Aashi's activity:
- Aashi measured the amounts of sodium carbonate and ethanoic acid as instructed.
- Aashi's activity is in agreement with the law of Conservation of Mass because the total mass of reactants (5.3 g + 6 g = 11.3 g) is equal to the total mass of products formed (2.2 g + 0.9 g + 8.2 g = 11.3 g).
Sheena's activity:
- Sheena did not measure the amounts of chemicals as instructed, so it is not possible to determine whether her activity is in agreement with the law of Conservation of Mass or not.
- It is possible that Sheena took amounts of chemicals that were not in the correct stoichiometric ratio, which would violate the law of Conservation of Mass.
Therefore, the correct answer is option B, Aashi's activity is in agreement with the law of Conservation of Mass.

- It is possible that Sheena took amounts of chemicals that were not in the correct stoichiometric ratio, which would violate the law of Conservation of Mass.
Therefore, the correct answer is option B, Aashi's activity is in agreement with the law of Conservation of Mass.
