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)
Answer:
You need 375 mL of BaCl2 solution.
Explanation:
M1V1=M2V2
Dilution formula. Substitute known values and solve for V1.
M1 = 2.0 M
M2 = 1.50 M
V2 = 500 mL
(2.0 M)(V1) = (1.50 M)(500 mL)
V1 = (1.50 M)(500 mL) / (2.0 M)
V1 = 375 mL
B - The reactants are the starting substances and the products are the end substances.
