In the formula 2NaOH, the number 2 is called a coefficient. It indicates that there are 2 moles of NaOH present in the compound.
Na2CrO4 (aq) + 2LiOH (aq) -----> Li2CrO4 (s) + 2NaOH (aq)
Sulfuric acid plus sodium hydroxide gives sodium sulfate plus water.
Mn(CH3COO)2 + 2NaOH ----> Mn(OH)2 + 2CH3COONa
There is one hydrogen atom in one formula unit of NaOH.
The balanced molecular equation for the reaction between ferrous sulfate (FeSO4) and sodium hydroxide (NaOH) is: FeSO4 + 2NaOH -> Fe(OH)2 + Na2SO4.
The balanced chemical formula for the reaction between iron(II) sulfate and sodium hydroxide is: FeSO4 + 2NaOH -> Fe(OH)2 + Na2SO4.
The formula is describing a chemical reaction where 2 molecules of sodium hydroxide (2NaOH) react with chlorine gas (Cl2) to produce sodium chloride (NaCl), sodium hypochlorite (NaClO), and water (H2O).
2NaOH (aq) + SrCl2 (aq) ==> NaCl (aq) + Sr(OH)2 (s)
Na2PbO2 It is obtained when PbO reacts with sodium hydroxide. PbO(s) + 2NaOH(aq) + H2O(l)-------> Na2PbO2 (aq) + H2O(l)
Cu(NO3)2 + 2NaOH >> Cu(OH)2 + 2NaNO3
H2SO3 + 2NaOH---------Na2SO3 + 2H2O
Na2CrO4 (aq) + 2LiOH (aq) -----> Li2CrO4 (s) + 2NaOH (aq)
2Na + 2H2O--->H2+ 2NaOH Hydrogen gas is diatomic, therefore it requires a subscript of 2.
Sulfuric acid plus sodium hydroxide gives sodium sulfate plus water.
The balanced chemical equation for the reaction between barium nitrate and sodium hydroxide is: Ba(NO₃)₂ + 2NaOH → Ba(OH)₂ + 2NaNO₃
Mn(CH3COO)2 + 2NaOH ----> Mn(OH)2 + 2CH3COONa
The balanced equation for the reaction between manganese(II) bromide and sodium hydroxide is: MnBr2 + 2NaOH → Mn(OH)2 + 2NaBr.
