<span>No of moles of Fe = Mass / Relative molar mass of Fe. So no of moles = 89.4/ 55.845 = 1.60. The. Chemical reaction is represented as follows. 4 Fe + 3 O2 which gives 2Fe2 O3 . This means that 4 atoms of Iron reacts with 3 atoms of Oxygen to produce Iron oxide. Hence 1.60*4 moles of Fe will need to react 1.6 * 3 moles of Oxygen to produce 2 moles of Iron oxide. Hence 4.8 moles of Oxygen will be required.</span>
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is 2(NH4)Cl + CuSO4.
Explanation:
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is
CuCl2 + (NH4)2SO4 ⇔ 2(NH4)Cl + CuSO4.
Here the left side one's are reactants i.e.,CuCl2 and (NH4)2SO4.
The right siders are products i.e.,(NH4)Cl and CuSO4.
The complete ionic equation is used to include both chemical species as well as spectator ions. It is used to indicate which of the reactants and products in the equation exists primarily as ions in aqueous solution.
It is nothing but a chemical equation in which electrolytes which are soluble in water are formed as dissociated ions.
The above chemical reaction is double displacement reaction.
I don’t know really sorry
