What is the balance equation for the reaction sodium hydroxide with water in an exothemic reaction?
Wiki User
∙ 11y ago
When solid sodium hydroxide dissolves in water, the water heats up, demonstrating that the process of dissolving is exothermic for NaOH. (Very exothermic, in fact, releasing about 45kJ of heat per mole dissolved -- enough to heat a liter of H2O by 10C!)
Since heat can be thought of as a product in an exothermic reaction, the equation is:
NaOH (s) ---> Na+ (aq) + OH_ (aq) + 45kJ

Why To balance a chemical equation can we change the formulae of either reactants or products?
if it is a redox reaction sometimes you can add water to help balance the equation
How do you balance a combustion reaction?
Combustion reaction equations balance the same way that any other chemical equation does. Every atom that appears on the left side of the equation must also appear on the right side of the equation. No atoms are created or destroyed in the process of a chemical reaction.
