How does fluorine electronegativity compare to the electronegativity of oxygen and chloride?
Artemon [7]

Answer:

Cl EN < O EN < F EN

Explanation:

Electronegativity is a periodic property that indicates the tendency of an atom to attract electrons when combined with another element. It is very useful for predicting the type of bonding of compounds, so it is not possible to talk about electronegativity in elements in a fundamental state.

In the periodic table the electronegativity increases diagonally and the values ​​were established in the so-called Pauling scale.  

It is expected that elements with high electron affinity and high ionization energy possess considered electronegativity, so the group of nonmetals have high electronegativity, in fact flour is the most electronegative element

Write a balanced equation for the complete combustion of solid palmitic acid. Remember that oxygen (O2(g)) is necessary for the
Alina [70]

Answer:

C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)

Explanation:

In order to determine a combustion reaction we should know that:

Reactants are: X compound and O₂

Products are: CO₂ and H₂O

In this case, the X compound is the solid palmitic acid: C₁₆H₃₂O₂

The balanced equation will be:

C₁₆H₃₂O₂ (s) + 22O₂(g) → 16CO₂(g) + 16H₂O(g)
