a complex ion: [Ni(NH3)6]
Nickel(II) is the plus two (+2) oxidation state of nickel (Ni), and we write it Ni(II) or Ni++ when we set it down.
NiCl2 + 2Na --> 2NaCl + Ni
Ni(s) | Ni2+(aq) Ag+(aq) | Ag(s)
The Iglesia ni Cristo (Church of Christ). Also the largest religious organization that made in the Philippines.
The chemical symbol for nickel is Ni.
The color of Ni(NH3)6^2+ is violet.
Ammonia reacts with nickel sulfate to form nickel(II) hydroxide, which is a pale green precipitate. This reaction is a double displacement reaction where the ammonia displaces the sulfate ion to form the precipitate.
Nickel forms Hydrogen gas when reacts with dilute acid.
The reaction between nickel nitrate [Ni(NO3)2] and ammonia (NH3) can form a complex compound known as hexaamminenickel(II) nitrate, which has the formula Ni(NH3)62. This compound consists of a nickel ion coordinated with six ammonia molecules in an octahedral geometry.
This reaction is known as the double exchange reaction Ni(NO3)2(aq) + 2 NaOH(aq) --> Ni(OH)2(s) + 2 NaNO3(aq) (aq) means in aqueous solution (s) means solid, hence nickel hydroxide is seen precipitating out of the solution
No reaction
A molecule Ni3 doesn't exist; you think probable to a compound of Ni(III).
2NaCl + Ni (for A+)
Ni + AlCl3
Your formulas are not correct.
NI(NO3)3+pbbr4nibr3+pb(no3)4
The unbalanced equation for the reaction is: Ni + Pb(NO3)2 -> Ni(NO3)2 + Pb
