Increasing order of magnitude of lattice energy is rbi <K2s< Mgs < Ga2O3.
Lattice energy is the energy change upon the formation of one mole of a crystalline ionic compound from its constituent ions. It depends upon the charges of the ion and the distance between the center of the ion when they are packed in the form crystal. Basically lattice energy is determined by the charge of the atom and the atomic radii of the atoms.
In Ga2O3, Ga has 3+ and O has 2- ions .so it has the lattice energy of 6.this is calculated by multiplying q1 and q2 .this attracts strongly.
In rbI , R has +1 and i has -1.so it ha lattice energy of -1.ther is no strong attraction nor lattice energy.
In Mgs, Mg has +2 and s has -2 .this is not as strong as Ga2o3 but stronger than rbi.
In K2S, k has =1 and s has 2-.this is stronger than rbi.

Hello,
A physical change describes a change that does physically and does not display “chemical” signs which are signs that indicate a precipitate being formed, change in color, density, or producing gas, etc. “Tearing a piece of paper in half” is a physical change because like I said earlier it doesn’t show any chemical change signs. I hope this helps you out!
Hi,
The answer should be C.
Hope this helps, if you’d like further explanation please let me know.
13.8 billion years ago
This relic radiation is known as the cosmic microwave background radiation. The chemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the universe was only 10–17 million years old.
