This is a double-replacement reaction. The charges of each cation and anion are:
Copper (II): 2+
Nitrate: 1-
Sodium: 1+
Hydroxide: 1-
This means that the equation without coefficients would be
Cu(NO3)2 + NaOH --> NaNO3 + Cu(OH)2.
Since there is an uneven number of nitrates and hydroxides, coefficients must be added before NaOH and NaNO3 to make the equation balanced.
Cu(NO3)2 + 2NaOH --> 2NaNO3 + Cu(OH)2The chemical reaction is: NH4NO3 + NaOH ---------→ NH3 + H2O + NaNO3
No reaction
No balance
Ca(NO3)2 + 2NaOH >> Ca(OH)2 + 2NaNO3
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
The balanced equation is: Ca(NO3)2 + 2NaOH → Ca(OH)2 + 2NaNO3
Al(NO3)3 + 3 NaOH --> Al(OH)3 + 3 NaNO3
Ba(NO3)2 + 2NaOH → Ba(OH)2 + 2NaNO3Barium nitrate + sodium hydroxide → barium hydroxide + sodium nitrate
The chemical reaction is: NH4NO3 + NaOH -----→ NH3 + H2O + NaNO3
The chemical reaction is: NH4NO3 + NaOH ---------→ NH3 + H2O + NaNO3
2KOH + Ba(NO3)2 -----> 2KNO3 + Ba(OH)2
No reaction
No balance
Cu(NO3)2 + 2NaOH >> Cu(OH)2 + 2NaNO3
Ca(NO3)2 + 2NaOH >> Ca(OH)2 + 2NaNO3
One balanced equation for the reaction between elemental copper and silver nitrate is Cu + AgNO3 -> CuNO3 + Ag.
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
