Aqueous solutions of lithium sulfate and calcium nitrate are mixed, forming the precipitate
Mashcka [7]

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)

if the theoretical yield of a reaction is 26.0 grams and you actually recovered 22.0 grams what is the precent yield
netineya [11]
Percentage Yield = (Actual Yield ÷ Theoretical Yield) × 100  

∴ if theoretical yield is 26 g, but only 22.0 is recovered from the reaction, 
then Percentage Yield = (22 g ÷ 26 g) × 100  
                                       =  84.6 %
