You're off to a good start, now find the mass of H2O and put it under I mol,
then multiply 1 mol over the mass of H2O by 215 grams
I think it’s A but I’m not sure.
I believe it is C; reasoning being that the hint for physical change is," the producing of a gas," chemical "that's new and diff. substance. "
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.
