A balanced equation has equal numbers of each type of atom on each side of the equation.The Balanced Ionic equation for Nitrous acid and sodium hydroxide is as follows .Nitrous acid is a weak acid so it does not completely dissociate in water. So you can write for the net ionic equation :
HNO2 + OH- ---> NO2- + H2O
HCl + NaOH --> NaCl + H2O
There is no reaction , because of the Common Ion Effect. The Common Ion is the Hydroxide.
Sodium hydroxide does not react with hydrogen gas.
NaOH + HCl >> NaCl + H2O
H3NSO3 + NaOH = NaSO3NH2 + H2O
2Zn3O2
HCl + NaOH --> NaCl + H2O
Na2O+H2O--->2NaOH
There is no reaction , because of the Common Ion Effect. The Common Ion is the Hydroxide.
Sodium hydroxide does not react with hydrogen gas.
NaOH + HCl >> NaCl + H2O
2Na + 2H2O -> 2NaOH + H2
2Na + 2H2O = 2NaOH + H2
It doesn't need balancing - it's already balanced. NaHCO3 + NaOH → Na2CO3 + H2O
The balanced equation is: Ca(NO3)2 + 2NaOH → Ca(OH)2 + 2NaNO3
This equation is HCl + NaOH -> NaCl + H2O.
H3NSO3 + NaOH = NaSO3NH2 + H2O
