Answer:
Option C. Na⁺(aq) and Cl¯(aq)
Explanation:
From the question given above, we obtained the following:
Na₂SO₄(aq) + CaCl₂(aq) —> CaSO₄(s) + 2NaCl(aq)
Ionic Equation:
2Na⁺(aq) + SO₄²¯(aq) + Ca²⁺(aq) + 2Cl¯(aq) —> CaSO₄(s) + 2Na⁺(aq) + 2Cl¯(aq)
From the ionic equation above, we can see that Na⁺(aq) and Cl¯(aq) are present on both side of the equation.
Therefore, Na⁺(aq) and Cl¯(aq) are the spectator ions because they did not participate directly in the reaction.
Explanation:
Scientist performs experiments as a process in the scientific method.
Experiments are quantitative and deliberate efforts towards testing an idea.
- Scientists perform experiment in order to validate or invalidate a proof.
- Also have more insight about the observation.
- To test an idea
- To gather information about something.
- To advance the pool of knowledge about a claim
