Question

A student decides to react HCl with NaOH in 50 g of H2O. The reaction produces heat.. What is the balanced chemical equation for the reaction?

Answer 1

`HCl(aq) + NaOH(aq) rarr NaCl(aq) + H_2O(l) + Delta_"rxn"`

Explanation:

Now not only does the given reaction observes stoichiometry with respect to atoms and molecules, it also observes stoichiometry with respect to the heat of reaction. `DeltaH` is usually reported per mole of reaction as written, and can usually be precisely measured.
