Read the following chemical equation. Mg(s) + H+ Cl− → Mg2+ Cl− + H2 What most likely happens during this reaction?

spin [16.1K]

Answer:

Magnesium loses two electrons.

Explanation:

As clear from the reaction Mg converted from Mg(s) to Mg²⁺, so Mg converted from the oxidation state (0) to (2+).

∴ Mg losses two electrons.

Cl⁻ remains as it is, so it is considered as a catalyst and neither loss nor gain any electrons.

So, the correct choice is Magnesium loses two electrons.

what modifications to either or both of the half-cell reactions would kim need to make if she wanted to use them to produce equa

kompoz [17]

We have to add the both half cell equations and eliminate the number of electrons lost/gained.

<h3>What modification must Kim make to the equations?</h3>

The term redox reaction is a type of reaction that occurs when an electron is lost or gained in a reaction system. We can see that in this reaction, zinc looses two electron which are gained by copper.

If we want to obtain the equation 4.9 which is the overall equation of the redox reaction from the various half cell equations then we have to add the both half cell equations and eliminate the number of electrons lost/gained.

In which orbitals would the valence electrons for selenium (Se) be placed?

RSB [31]

Selenium falls in the same column with oxygen therefore it has the same number of valence electrons with oxygen which is 6. It fills the 3d orbital but only 4s and 4p are counted. The electronic configuration is [Ar]3d^10 4s^2.
