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)
Correct Answer: option 1 i.e. C
Reason:
The the compound of interest i.e. XCl4, since there are 4 Cl atoms bonded to X. This signifies that the valency of X is 4.
There atomic number of C is 6. It's electronic configuration is giving by 1s2 2s2 2p2. Thus, there are 4 electrons in valence shell of C. This signifies that valency of C is 4. Hence the compound present in present case is CCl4.
Stored mechanical energy is energy stored and awaiting to be used and mechanical energy is the energy that was stored being used.
