Question #9322b

Answer 1

`"NiCl"_2("aq)" + "NaOH(aq)"` `rarr` `"Ni(OH)"_2"(s)" + "NaOH(aq")`

Explanation:

This is a double replacement (double displacement) reaction in which the cations and anions of the two reactants switch places. It can be represented by the following example:

AX + BY`rarr`AY + BX

Where A and B are cations and X and Y are anions.

We can now predict the products of this reaction.

`"NiCl"_2("aq)" + "NaOH(aq)"` `rarr` `"Ni(OH)"_2"(s)" + "NaOH(aq")`
