A solution of calcium chlorate was poured into a sodium fluoride solution. Would you expect a precipitate to form if 255.0 mL of
the calcium chlorate solution (2.0x10-5 M) was mixed with 300.0 mL of a 2.5x10-3 M sodium fluoride solution? A. No, because Qsp < Ksp for calcium fluoride B. Yes, because Qsp < Ksp for calcium fluoride C. Yes, because Qsp = Ksp for sodium chlorate D. Yes, because Qsp = Ksp for calcium fluoride E. No, because Qsp = Ksp for sodium chlorate F. No, because Qsp < Ksp for sodium chlorate G. No, because Qsp > Ksp for calcium fluoride H. No, because Qsp > Ksp for sodium chlorate I. Yes, because Qsp < Ksp for sodium chlorate J. No, because Qsp = Ksp for calcium fluoride K. Yes, because Qsp > Ksp for sodium chlorate L. Yes, because Qsp > Ksp for calcium fluoride

Answer:
1 .
2.
Explanation:
The more stable the ionic compound, the more is it lattice energy.
- The more the charge on the cation and the anion, the greater is the lattice energy.
- The less the size of the cation and the anion, the greater is the lattice energy.
Scandium oxide () is an oxide in which
behaves as cation and
behaves as anion.
The compounds which has higher lattice energy than scandium oxide are:
1 .
This is because the charge are same on the cation and the anion as in the case of the Scandium oxide but the size of the cation is smaller than
. Thus, this corresponds to higher lattice energy.
2.
This is because the charge on the cation is greater than that of
and also the size of the cation
is smaller than
. Thus, this corresponds to higher lattice energy.
Answer :
Explanation :
The aluminium and fluorine react to give ionic compound aluminium fluoride.
Aluminium has 1 valence electrons in their shell and fluorine has 7 valence electrons in their shell.
For the complete octet, both aluminium and fluorine exchange valence electrons to form an ionic compound.
The aluminium donates its three valence electrons to three fluorine atoms and they form one and three
ions.
Electron transfer image is shown below.
