Answer:
Explanation:
The formula of nickeI(II)nitrate hexahydrate is
Ni(NO3)2.6H2O
So option (c) is correct.
Answer:
C) Ni(NO₃)₂.6H₂O
Explanation:
Given:
Formula name : nickel(II)nitrate hexahydrate
To determine:
The molecular formula
Explanation:
In the given compound:
Nickel is a transition metal with the symbol Ni and occurs as a cation
Nitrate is a polyatomic anion with a charge -1 i.e. NO₃⁻
The roman numeral 'II' implies that the oxidation state of Ni is +2
Since the compound is neutral the charge on the cation and anion needs to be balanced. As a result the molecular formula is: Ni(NO₃)₂
Hexahydrate implies that there are six (hexa) molecules of water of hydration
The formula is therefore: Ni(NO₃)₂.6H₂O
