Answer:
Carbon
Explanation:
I just finished this and that's what I got from my periodic table.
Answer:
The valence electrons in the metal atom in the lattice structure can delocalize and move freely. The electrons are "loosely" connected with their parent atom in the metallic bond because most metals have excess electrons in their outer orbitals above the stable configuration.

Answer:
The mass of an object is the same no matter where it is, but the weight of an object changes with the location of that object. For example, the weight of an object on the Moon is 1/6th that of the same object on Earth, while the mass of that object is exactly the same in both places.

Answer:
is the solubility of 
in 0.10 M 
.
Explanation:
Concentration of calcium nitrate = ![[Ca(NO_3)_2]=0.10 M](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M)
![[Ca(NO_3)_2]=0.10 M=[Ca^{2+}]](https://tex.z-dn.net/?f=%5BCa%28NO_3%29_2%5D%3D0.10%20M%3D%5BCa%5E%7B2%2B%7D%5D)
Solubility product of the calcium fluoride = 
Solubility of calcium fluoride in calcium nitrate solution :
(0.10+S) (2S)
The expression of solubility is given by :
![K_{sp}=[Ca^{2+}][F^-]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2)
Solving for S:
is the solubility of in 0.10 M .
The only information in this problem that we are given with are the stoichiometric coefficients in the reaction, and the rate of disappearance of NH₃ as 0.05 M/s. The rate of disappearance always has a negative sign. The general formula would be:
Rate of Reaction = -(ΔNH₃/Δtime)(1/v), where v is the stoichiometric coefficient of NH₃ in the reaction
Substituting the values,
Rate of Reaction = -(0.05 M/s)(1/4) = <em>-0.0125 M/s</em>
