Which of the following statements about the following chemical equation is 1 point correct? *
Zn + 2HCI —— ZnF, + H,
1 The equation is correctly written because all of the elements on the reactant side are
also found on the product side.
2 The equation is NOT correctly written because all of the elements on the reactant side
are also found on the product side.
3 The equation is NOT correctly written because some of the elements on the reactant
side are NOT found on the product side.

Explanation:

Some metals react with acid and replace hydrogen from the acid.

since they are more reactive than hydrogen in the electro - chemical reactivity series.

so here Zinc is acting as reducing agent or called reductant.

and Hydrogen ion is acting as an oxidant.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
