Gravitational attraction exists between all objects in the universe. Which word, if any, should replace "all" in this statement
o-na [289]

Answer:

What is the empirical formula of the compound with the molecular formula c18h36?
emmasim [6.3K]
When we write a formula of a compound in its simplest form, it is empirical formula.
Given the molecular formula is = C₁₈H₃₆
Now we can relate both empirical and molecular formula as;
Molecular formula = n x empirical formula
C₁₈H₃₆ = 18 x CH₂
So the empirical formula of C₁₈H₃₆ is CH₂

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+}

Sulfite ion is a polyatomic ion having a chemical formula of SO_3^{2-}

An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of XSO_3

Hence, the chemical formula is XSO_3
