Chemistry

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)

$\qquad \tt \rightarrow \:2.8 × {10}^{-5}$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: \dfrac{2.36 \times 10 {}^{ - 2} }{8.4 \times {10}^{2} }$

$\qquad \tt \rightarrow \: \dfrac{2.36 }{8.4 } \times \cfrac{10 {}^{ - 2} }{10 {}^{2} }$

$\qquad \tt \rightarrow \: 0.28 \times 10 {}^{ - 2 - 2}$

$\qquad \tt \rightarrow \: 0.28 \times 10 {}^{ - 4}$

$\qquad \tt \rightarrow \: 2.8 \times 10 {}^{ - 5}$
