the balanced chemical equation for one neutralization reaction. In your equation, which reactant contributed the salt's positive ion? Which one contributes the salt's negative ion?

See the answer below

Explanation:

A neutralization reaction is a reaction that involves acid and base with the production of salt and water as the end products. An example is as below:

HCl + NaOH --> NaCl + H2O

The salt produced here is NaCl. In solution, NaCl will ionize as:

Hence, the salt's positive ion (Na+) was contributed by the base (NaOH) while its negative ion (Cl-) was contributed by the acid (HCl).

c is the answer because when something is left after something evaporates that shows the chemical change.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
