It doesn't need balancing - it's already balanced.
NaHCO3 + NaOH → Na2CO3 + H2O
When sodium hydroxide reacts with calcium bicarbonate, it forms sodium bicarbonate and calcium hydroxide. The balanced chemical equation for this reaction is 2NaOH + Ca(HCO3)2 -> 2NaHCO3 + Ca(OH)2.
Any reaction occur.
Balanced:2 KOH + SO3 ----> K2SO4 + H2O
The balanced equation for the reaction between salicylic acid and sodium hydroxide is: C7H6O3 + NaOH → C7H5NaO3 + H2O
The balanced equation for the reaction of a fatty acid (such as stearic acid) and sodium hydroxide is: C17H35COOH + NaOH -> C17H35COONa + H2O This reaction produces a salt (sodium stearate) and water.
The balanced equation for the reaction of castor oil (triglyceride) and sodium hydroxide (NaOH) is: Triglyceride + 3NaOH → Glycerol + 3Soap This reaction is known as saponification, which produces glycerol and soap molecules from the reaction between the ester bonds in the triglyceride and the hydroxide ions in sodium hydroxide.
The balanced equation for the reaction between amidosulfuric acid (NH2SO3H) and sodium hydroxide (NaOH) is: NH2SO3H + NaOH → NaHSO3 + H2O
The balanced equation for the reaction between hydrochloric acid (HCl) and potassium hydroxide (KOH) is: HCl + KOH -> KCl + H2O
Simplified. 2NaOH + H2SO4 -> Na2SO4 + 2H2O
There is no reaction between zinc hydroxide and sodium hydroxide.
The balanced equation for the reaction between a fatty acid (such as oleic acid) and sodium hydroxide is: Fatty acid + Sodium hydroxide -> Soap (sodium salt of the fatty acid) + Water
Stearic Acid + Sodium Hydroxide = Sodium Stearate (soap) + Water. C18H36OOH + NaOH = C18H36OONa + H2O
