Praseodymium bromide is an inorganic compound with the chemical formula Pr(BrO3)3. It is soluble in water and can form the dihydrate, tetrahydrate[1] and nonahydrate. The nonahydrate melts in its own crystal water at 56.5 °C and completely loses its crystal water at 130 °C.[2] It can be produced by the reaction of barium bromate and praseodymium sulfate.[3]

Combinatorial game theory concept to represent all possible game states For game tree as it is used in game theory (not combinatorial game theory), see Extensive-form game. In the context of combinatorial game theory, which typically studies sequential games with perfect information, a game tree is a graph representing all possible game states within such a game. Such games include well-known ones such as chess, checkers, Go, and tic-tac-toe. This can be used to measure the complexity of a ga...
