Answer:
oxalate, fluoride, carbonate, phosphate.
Explanation:
It is important to consult the solubility chart in order to determine the anions.
Any compound with a low Ksp means the compound is very insoluble.
Hence, it means the formation of this compound is favoured strongly and its dissolution which would liberate calcium ions is unfavoured.
Any compound with a low Ksp would therefore "soak up" all the free calcium and will thus not be present in the solution.
Using solubility chart and noting the compounds with a low Ksp value, the anions that are probably present are: oxalate, fluoride, carbonate, phosphate.

Answer:
2 molecules of water
Explanation:
In chemical reactions, molecules and compounds chemically combine to give products. This involves atoms combining by re-establishing bonding relationships.
4 hydrogen atoms is equivalent to 2 molecules of Hydrogen gas = H₂
2 oxygen atoms is the same as 1 oxygen molecule = O₂
This 2 molecules of hydrogen gas and 1 molecule of O₂ gas will combine to form 2 molecules of water chemically;
2H₂ + O₂ → 2H₂O
Answer:
A tick living on a dog and drinking it's blood = Parasitism
Birds that live among cattle too eat insects stirred up by grazing = Mutualism
A clownfish living on the tentacles of an anemone provides nutrients too the anemone, and the clownfish is protected from predators = commensalism
A bear catching and eating a salmon from the river = predation
A bobcat catching and eating a rabbit = predation
A tapeworm living on the digestion system of a horse = parasitism
A Egyptian plover eating bugs off a giraffe or rhino = Mutualism
Bees gathering nectar and then spreading pollen too a flower = commensalism
