In the reaction zn h right arrow. zn2 h2, zn is oxidized and h is reduced. how many electrons would be produced and used in the balanced half-reactions? complete the balanced half-reactions: h e– right arrow. h2 zn right arrow. zn2 e–

Respuesta :

2-electrons would be produced and used in the balanced half-reactions.

Completing the balanced half-reactions:

For hydrogen:

2 H⁺ + 2 e → 1 H₂.

For Zinc:

1 Zn → 1 Zn²⁺ + 2 e.

So, it can be observed clearly that hydrogen absorbs 2 electrons and zinc releases 2 electrons. Thus, an exchange of 2 electrons takes place.

Balancing Chemical Reactions:

The changes that take place during a chemical reaction are depicted by a chemical equation. A general form of a chemical equation is:

Reactants → Products

A considerable degree of trial and error is involved in balancing a chemical equation. But generally, you should do the following:

  • Take an inventory of the atoms in the reactants and products. Do both sides of the arrow have the same number of each atom? If not, then step 2 is required since the equation is not balanced.
  • In order to increase the number of atoms or molecules in the substances, add coefficients as necessary in front of the symbols or formulae. The lowest coefficients are to be used.
  • Warning! In chemical formulations, subscripts should never be changed. Changing subscripts changes the substances involved in the reaction. Change only the coefficients.
  • Repeat steps 1 and 2 until the equation is balanced.
