The epicenter is determined to be located on a circle that is centered around Recording station X, with a radius extending 250 km.
Response: Option A) The lattice energy rises as cations become smaller, as demonstrated by LiF and KF.
Clarification: It has been observed that the lattice energy is largely determined by two primary factors regarding ionic solids:
i) The ionic charges - An increase in the charge of the ions corresponds to an increase in lattice energy.
and
ii) The size or radius of the ions - As the ionic size grows, the lattice energy diminishes accordingly.
Therefore, in this context, the latter factor is evident. Thus, it can be concluded that as cation sizes decrease among ionic solids, the lattice energy increases.
The soccer field's length is 3.94 × 10^2 in.
Length = 100 m × (39.37 in/1 m) = 394 in = 3.94 × 10^2 in
