Cations from smallest to largest
Li⁺ ,Na⁺, K⁺ (from Periodic Table, the bigger number of period, the bigger size, of atom, so the bigger size of cation)
1) LiF smaller cation then KF
1,036 <span>853
</span><span>The lattice energy increases as cations get smaller, as shown by LiF and KF.
</span><span>I think this one should be correct answer, because the compared substances have also the same anion, and we can compare cations in them.
2) The same cation Li , so wrong statement.
3)</span>The same cation Na , so wrong statement.
4) NaCl smaller cation then KF
786 853
Answer:
5m3
Explanation:
becuase density= mass/volume
rearrange to make = volume=mass/density
15/3= 5
Answer:
True
Explanation:
It is true that every element in the periodic table follows the Aufbau's principle.
The principle states that "the sublevels with lower energies are filled up before those with higher energies".
- Sublevels do not fill up in numerical order.
- This is true when writing the electronic configuration of all atoms on the periodic table.
Answer: 64.8
Explanation:Please see attachment for explanation
The given reaction is
2 SO2 + O2 <=> 2 SO3, for which kp = 2 at a given temperature
Equilibrium constant = pSO3^2 / pSO2^2 X pO2
Q= (3.4)^2 / (2.2)^2 X 1.6 = 1.5
As Q< Kp
The reaction is not at equilibrium and reaction will go in forward direction
