These substances doesn't react.
The Cu2+ from CuSO4 is displaced by the Na+ from NaCl and CuCl2 and Na2SO4 are formed.
AgNO3(aq) + NaCl(aq) --> AgCl(s) + NaNO3(aq)
Salt and water are formed NaOH + HCl --> NaCl + H2O
Dissociation products of sodium chloride are the cation Na+ and the anion Cl-.
Assuming you mean a reaction between potassium (K) and copper(II) sulfate, your products would be potassium sulfate and copper in a single replacement reaction. Here's the equation:2K + CuSO4 --> K2SO4 + Cu
You get a sodium sulfate deposit.
CuSO4 + 2HCl -> CuCl2 + H2SO4 copper chloride and sulfuric acid
I think they are called a product. e.g. Na+Cl becomes NaCl
When acid and base combine, they give a salt and water. NaOH + HCl -------> NaCl + H2O.
carbon dioxide, salt and water eg 2HCl + Na2Co3 -> NaCl + Co2 + H2O
Copper sulphate CuSO4
C12H22O11 is the Disaccharide Sucrose (table sugar). The other three are salts.
