What is the standard cell potential of a cell made of theoretical metals ma/ma2+ and mb/mb2+ if the reduction potentials are –0.
Yuki888 [10]
The standard cell potential of a cell made of theoretical metals ma/ma2+ and mb/mb2+ is to be determined. We are given their reduction potentials:

-0.19 v for A
-0.85 v for B

To solve for the standard cell potential, examine the reaction and

the standard cell potential for this case is (-0.19- (-0.85)) v = -0.66 v<span />

Which element among these has the most negative electron affinity (i.e., has most exothermic electron affinity). A. H B. Li C. C
OleMash [197]

Answer:

D. F

Explanation:

Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.

The electron affinity values of the following elements is given;

Electron Affinity of Hydrogen is 72.8 kJ/mol.

Electron Affinity of Lithium is 59.6 kJ/mol

electron affinity of carbon is 153.9 kJ mol‑1

Electron Affinity of Fluorine is 328 kJ/mol

The electron affinity of neon is 0 kJ mol‑1.

When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.

Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.

That explains why florine seems to have the highest electron affinity value.

Jill then wrote the formulas for all the possible compounds that sodium can form with the other ions. What formulas did she writ
sp2606 [1]

Explanation:

Sodium has atomic number of 11 and its electronic configuration is given by:

[Na]=1s^22s^22p^63s^1

The nearest stable electronic configuration to sodium is of the neon. So, in order to attain stability of noble gas it will loose its single electron.

Na\rightarrow Na^++1e^-

[Na^+]=1s^22s^22p^63s^0

Sodium has single valency that is 1.

Let nbe the valency of the ion 'X'

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

Na_nX_1

So, the formulas for all the possible compounds that sodium can form with the other ions will be:

Na_nX_1
