Trisulfur nonaiodide
Step-by-step explanation:
The name for a binary molecular compound has the form
Multiplying prefix+name of first element multiplying prefix+stem of second element element+ide (two words)
The multiplying prefixes for three and nine are tri and nona, respectively.
The stem of iodine is iod.
Put them together, and the name of S₃I₉ is
trisulfur nonaiodide.
The metal that will react is Cobalt.
The equation for the reaction is,
Co + Ni(NO3)2 → Co(NO3)2 + Ni
The above reaction is an example of Displacement Reaction. Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound.
Cobalt is more reactive than Nickle in the reactivity series so it displaces Nickle from Nickle Nitrate and forms Cobalt Nitrate.
Reactivity series is a list of metals arranged in decreasing order of their reactivity. The metals with the greatest reactivity are at the top, followed by those with the lowest reactivity. Higher-ranking metals in a series can force lower-ranking metals out of their salt solution for any two metals in the series.
