Answer:
No, it isn't a spontaneous reaction.
Explanation:
A spontaneous reaction is a reaction that requires no outside intervention to start.
All chemical reactions require energy.

First you need to write out the original equation.
It needs to be balanced, though, so after balancing it should look like this:
The ionic equation would look like this. (Only aqueous solutions can be split up).
The net ionic equation only contains the products that are not aqueous. Therefore, the final net ionic equation should be:
So your answer is C.
<u>A solution of NaF is added to a solution that is 0.0144 M in Ba²⁺. When the concentration of F- exceeds </u><u>0.011 m, BaF₂</u><u> will precipitate.</u>
Let's consider the solution of BaF₂.
BaF₂(s) ⇄ Ba²⁺(aq) + 2 F⁻(aq)
We can use the solubility product constant (Ksp) to find the equilibrium concentration of F⁻ when [Ba²⁺] is 0.0144 M.
When [F⁻] exceeds 0.011 M, BaF₂ will precipitate.
A solution of NaF is added to a solution that is 0.0144 M in Ba²⁺. When the concentration of F- exceeds 0.011 M, BaF₂ will precipitate.
What is BaF₂.?
- BaF2 crystallizes in the cubic Fm3m space group and has a fluorite structural makeup.
- Eight comparable F1 atoms and Ba2+ are joined in a cubic shape with the body in the middle. The average Ba-F bond length is 2.72.
- Four comparable Ba2+ atoms are joined with F1 to create a mixture of corner- and edge-sharing FBa4 tetrahedra.

Answer:
true
covalent bonds are between non metals and nonmetals. and they are sharing electrons.
