Answer:
BaSO₄
Step-by-step explanation:
Hello,
In this case, one could determine the compound most likely to be dissolved in water by locating the main nonmetal in the periodic table, thus, the farthest one from barium will lead to the formation of the most polar or ionic bond, which will be the most soluble, in such a way, since sulfur is farther than both carbon and phosphorous, BaSO₄ will be the compound most likely to be dissolved in water.
Best regards.
