Locate the ion that has no change in oxidation number in redox reactions.
a. What is the term applied to an ion that is present but does not enter into the actual chemical
reaction?
b. What ion in this equation is this type of ion?

a. Spectator ions are the ones that are present but does not enter into the actual chemical  reaction.

b. Na⁺ and NO₃⁻ ions are spectator ions involved in this above mentioned reaction

Explanation:

This can be expressed as the following equation,

AgNO₃(aq) + NaCl(aq) →AgCl(s) + NaNO₃

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
