Answer:

The answer to your question is the letter d.

Explanation:

Data

                Zn  +  HCl   ⇒  ZnCl₂  +  H₂

- Calculate the Oxidation number of reactants and products

              Zn⁰  +  H⁺¹Cl⁻¹   ⇒  Zn⁺²Cl₂⁻¹  +  H₂⁰

- Determine which elements changed their oxidation numbers

                      Zn⁰     ⇒   Zn⁺²                Zn lost 2e⁻

                     2H⁺¹      ⇒   H₂⁰                H won 2 e⁻

-Interchange the electrons lost and won

                  2( Zn⁰     ⇒   Zn⁺²)

                  2(2H⁺¹      ⇒   H₂⁰)

-Simplify

                  2Zn⁰     ⇒   2Zn⁺²

                  4H⁺¹      ⇒   2H₂⁰

-Substitute the coefficient in the equation

                2Zn  +  4HCl   ⇒  2ZnCl₂  +  2H₂  

             Reactant       Element      Product

                  2                    Zn                2

                  4                     H                 4

                  4                     Cl                 4

- Now the reaction is balanced

What is a saturted solution
andrew-mc [135]

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

What is ejected from the nucleus during alpha decay?
Aloiza [94]
Hi

Alpha decay is a type of radioactive decay.
So, when Alpha decay goes through a process called "radioactive process", two neutrons and two protons comes together and is ejected from the nucleus of a radioactive atom.

Hope this helped :)
