You are correct. Boron Sulphide will even react with atompheric water so has to kept away from air.
B2S3(s) + 6 H2O (l) ---> 3 H2S(g) + 2H3BO3(aq)
Cesium reacts violently with water, forming cesium hydroxide and releasing hydrogen gas.
sodium sulfide is apparently made by generating hydrogen sulfide gas into a sodium hydroxide solution,and then adding an equivalent alkali. you would get sodium sulfide if you added an equivalent alkali to the solution.
Cesium reacts violently with water, oxygen and the halogens
Hydrogen, H2
B2S3(s) + 6 H2O (l) ---> 3 H2S(g) + 2H3BO3(aq)
Cesium reacts violently with water, forming cesium hydroxide and releasing hydrogen gas.
The rubidium reacts violently, producing hydrogen gas and a rubidium salt. If oxygen is present the heat from the reaction may ignite the hydrogen.
Rubidium reacts violently (and does not explode,) to produce Rubidium Hydroxide and Hydrogen.

umm it reacts violently in water. so it may be "soluble" but it reacts rather violently
Potassium violently reacts with hydrochloric acid forming the potassium chloride and hydrogen gas.
Cesium reacts violently with water, oxygen and the halogens
It reacts rapidly but not violently unless heated.
Because it contains Sulfur and sulfur reacts with the silver forming hydrogen sulfide, which causes the tarnish
Hydrogen, H2
