This chemical equation represents a chemical equation. 2HNO3 + Na2SO3 → 2NaNO3 + H2O + SO2

Which chemical is a reactant in the reaction?

a. H2O
b. Na2SO3
c. SO2
d. NaNO3

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
