Answer:

2NaI + F₂ → 2NaF + I₂

Explanation:

Chemical equation:

NaI + F₂ → NaF + I₂

Balanced chemical equation:

2NaI + F₂ → 2NaF + I₂

The given reaction is single replacement reaction.

Step 1:

NaI + F₂ → NaF + I₂

left hand side Right hand side

Na = 1 Na = 1

I = I I = 2

F = 2 F = 1

Step 2:

2NaI + F₂ → NaF + I₂

left hand side Right hand side

Na = 2 Na = 1

I = 2 I = 2

F = 2 F = 1

Step 3:

2NaI + F₂ → 2NaF + I₂

left hand side Right hand side

Na = 2 Na = 2

I = 2 I = 2

F = 2 F = 2

the first three ionization energies of an element x are 590, 1145, and 4912 kj mol-1. what is the most likely formula of the com

joja [24]

<u>Answer:</u> The chemical formula is $XSO_3$

<u>Explanation:</u>

Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.

The ionization energy equation for the given values follow:

$X(g)\rightarrow X^+(g)+e^-;E_I=590kJ/mol$

$X^+(g)\rightarrow X^{2+}(g)+e^-;E_I=1145kJ/mol$

$X^{2+}(g)\rightarrow X^{3+}(g)+e^-;E_I=4912kJ/mol$

From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.

Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.

This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.

Hence, the ion formed will be $X^{2+}$
