Answer:
50?
I think but not 100% sure if not lmk
A solution means that you're trying to solve (or deal) with a situation.
For example, if you're having trouble trying to solve a math problem, that means that you're trying to figure out that problem.
Answer:
Here are key points on lattice energy
Lattice energy (L.E) is the energy required to separate a mole of an ionic solid into gaseous ions.
• L. E cannot be measured empirically, but it can be estimated using the Born-Haber cycle or calculated using electrostatics.
• The charge and radius of the bonded ions are two main factors that contribute to the magnitude of the L.E.
Explanation:
About the trend Yes/No are included to the details.
a)
1. True - (as charge increases, lattice energy increases)
2. False - (Oxide and chloride both have -1 charge)
3. False (The chloride ion is bigger having a bigger radius)
4. False - (the charges quoted are incorrect )
5. True
(b)
1. True - (it has the smallest radius)
2. True
3. False (the ion in all are +1 and -1)
4. False
5. False
6. False
(c)
1. False - ( BaO +2 and -2 while KF +1 and -1)
1. False - ( BaO +2 and -2 while KF +1 and -1)
2. True
3. False
4. True
5. True
Answer:
Formal Charge for H, O, F, O = 0,0,1,-1
While an octet of electrons is attained by the oxygen and fluorine atoms in this structure and the formal charges add to zero, having to assign a formal charge of +1 to such an electronegative atom as fluorine may indicate that such a structure is not likely to occur. In fact, fluorine commonly only forms one oxyacid, HOF.
