Explanation:
the breakdown of a compound into oppositely charged ions
Answer:
(aq) Li2SO4 + (aq) Ca(NO3)2 --> (s) CaSO4 + (aq) 2LiNO3
Explanation:
Aqueous Lithium Sulfate is Li2SO4
Aqueous Calcium Nitrate is Ca(NO3)2
When they're mixed, we get the double displacement solution Calcium Sulfate and Lithium Nitrate.
Precipitate is solid.
We got solid Calcium Sulfate so the other solution must be aqueous.
CaSO4 (s) --> Calcium Sulfate product
LiNO3 (aq) --> Lithium Nitrate product
We balance equation now. 2 Lithiums total and 2 Nitrates total. (Cuz there are 2 on the other side, 1 here)
37.5 for median ( first organize from least to greatest, elimate from each side until you get to center then add two numbers and divide by two.) Hope that helps.
