The solubility of sodium nitrate in water is 0.8g/mL at 0 degrees Celsius. The solubility increases to 1.9g/mL at 180 degrees Celsius. Using the particle theory of matter, explain why this happens.

*PLEASE EXPLAIN AND ALSO USE THE PARTICLE THEORY OF MATTER for brainliest answer! ;)

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?

Phosphorous can form an ion called phosphide, which has the formula p3−. this ion can form an ion called phosphide, which has the formula p3−. this ion properties very similar to those of pforms when a phosphorus atom loses three protonsis called a cationcontains 18 electrons
