It would be: 1s2, 2s2, 2p4
Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
The difference in the concentration of a substance between two areas is called the concentration gradient. When a region has a higher particle concentration than another, this is known as a concentration gradient. A concentration gradient will cause particles in passive transport to diffuse down it from higher concentration to lower concentration until they are evenly spaced.
The gradual separation of a region of high density from a region of low density in a solution in terms of the concentration of a dissolved material. Understanding how ions and particles flow randomly in a solution or gas depends on the concentration gradient.

Answer:
Option (B) 6270J
Explanation:
The following were obtained from the question:
M = 100g
T1 = 30°C
T2 = 45°C
ΔT = 45 —30 = 15°C
C = 4.18J/g°C
Q=?
Q = MCΔT
Q = 100 x 4.18 x 15
Q = 6270J
Therefore, the total amount of heat absorbed is 6270J
