nickel(ii) nitrate is prepared by heating nickel metal with liquid dinitrogen tetroxide. in addition to the nitrate, gaseous nitrogen monoxide is formed.write the balance equation​

Answer 1

nickel(ii) nitrate is prepared by heating nickel metal with liquid dinitrogen tetroxide and addition to the nitrate, gaseous nitrogen monoxide is formed.

chemical formula of nickel(II) nitrate = $Ni(NO_3)_2$

chemical formula of dinitrogen tetraoxide = $N_2O_4$

chemical formula of nitrogen monoxide = $NO$

so, skeleton chemical reaction is ...

$Ni(s)+N_2O_4(l)\rightarrow Ni(NO_3)_2(s)+NO(g)$

and now balanced chemical reaction is ...

$Ni(s)+2N_2O_4(l)\rightarrow Ni(NO_3)_2(s)+2NO(g)$

Answer 2

Answer:

The balanced chemical reaction is

$\mathrm{Ni}(\mathrm{s})+2 \mathrm{~N}_{2} \mathrm{O}_{4}(\mathrm{l}) \rightarrow \mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{~s})+2 \mathrm{NO}(\mathrm{g})$.

Explanation:

A balanced equation exists an equation for a chemical reaction in which the number of atoms for each element in the reaction and the entire charge exist the exact for both the reactants and the products.

Chemical formula of nickel (II) nitrate $=\mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}$

Chemical formula of dinitrogen tetraoxide $=\mathrm{N}_{2} \mathrm{O}_{4}$

Chemical formula of nitrogen monoxide $=N O$

so, skeleton chemical reaction is

$\mathrm{Ni}(s)+\mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{l}) \rightarrow \mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}(s)+\mathrm{NO}(g)$

and now the balanced chemical reaction is

$\mathrm{Ni}(\mathrm{s})+2 \mathrm{~N}_{2} \mathrm{O}_{4}(\mathrm{l}) \rightarrow \mathrm{Ni}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{~s})+2 \mathrm{NO}(\mathrm{g})$.
