The correct formula of the oxide that forms when X burns in oxygen is X2O3.
Ionization energy is defined as the energy required to remove an electron from an atom. There are as many ionization energies present in an atom as there are electrons in that atom.
However, we can know the ionization energy values that belong to electrons in the outermost shell because they lie close together. If we go further into the inner shells, there is a sudden quantum jump in ionization energy values.
The element X must have three valence electrons because 631 ,1235, 2389 all refer to ionization energies of electrons in the valence shell. As we get into a core shell, there is a sudden jump hence the fourth and fifth ionization energies are 7089 and 8844 respectively.
The correct formula of the oxide that forms when X burns in oxygen is X2O3.

From the equation of the graph, the activation energy of the reaction is -2.2 * 10⁴ J/mol.
<h3>What is activation energy?</h3>
Activation energy is the minimum required energy that reactant molecules must possess for a reaction to proceed towards formation of products.
The activation energy is determined from the slope of ln k against 1/T(K).
Given the equation, y = -2.2 * 10⁴ x + 45.0.
Comparing with the equation of a straight line, y = mx + c
The gradient, m = -2.2 * 10⁴
Therefore, the activation energy of the reaction is -2.2 * 10⁴ J/mol.
In conclusion, reactant molecules must break the activation energy barrier in order to form products.
