Answer:
The answer to your question is Na₂S, if you need to choices the other one is BaS
Explanation:
As a general rule, all the compounds that have sulfur, are insoluble in water, but the are some exceptions.
-Molecules with ammonia
-If the molecule has alkali metals is soluble
-If the molecule has Ca⁺², Sr⁺² and Ba⁺² is soluble in water.
From the compounds given, following the rules, the compound that is soluble in is Na₂S and perhaps BaS.
A cell is highly efficient in fulfilling an extensive variety of tasks all by itself. Numerous processes, like transport, protein formation, cellular respiration, etc. take place inside the cell. These different functions are essential for an organism to be able to survive, and these can be accomplished by the cell due to the specialized functions and role of the organelles. The cell organelles execute their functions in order to help with the survival of the cell. The ribosomes help in protein formation, the mitochondria generates ATP and the phagocytes carry out phagocytosis. These specialized functions are very helpful so that a cell could perform a lot of functions.
Electron is the correct answer :D
