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:
Methanol is more acidic than the alkyne and will be deprotonated instead.
Explanation:
of methanol is around 15 and of terminal alkyne is around 26.
, where is acid dissociation constant
So, higher the acidity of an acid, higher will its value and thereby lower will be its value.
So, methanol is certainly stronger acid than terminal alkyne.
Hence sodium amide preferably deprotonates methanol instead of terminal alkyne.
Hence, option (A) is correct.
Hey there!:
Molar mass CO2 = 44.01 g/mol
44.01 g CO2 ------------------- 6.02*10²² molecules CO2
88 g CO2 ------------------------ y
y = 88 * ( 6.02*10²² ) / 44.01
y = 5.29*10²⁵ / 44.01
y = 1.2 * 10²⁴ molecules of CO2
Answer A
Hope that helps!
