Answer:
c 3 mol of Ba(OH)₂ and 1 mol of Ba₃N₂ should be interchanged
Explanation:
Ba₃N₂ + 6H₂O → 3Ba(OH)₂ + 2NH₃
n/mol: 9.2

They want to find moles of Ba₃N₂, so that should be in the numerator of the conversion factor,
Moles of Ba(OH)₂ should be in the denominator to cancel the units in 9.2 mol Ba(OH)₂,
The right answer is animal-like.
Protists are unicellular living organisms about 0.1 mm in size, such as amoeba, paramecium and euglena.
Protists are a paraphyletic group in the phylogenetic classification. They were, in classical classification, the fourth reign of the domain of eukaryotes but they are currently defined by exclusion, that is to say that they are all eukaryotes belonging neither to mushrooms nor to plants or animals.
