If the solubility of a gas in water is 2.4 g/l when the pressure of the gas above the water is 5.0 atm what is the pressure of the gas above the water when the solubility of the gas is 1.0 g/l

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

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?

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?
