Lewis structure, which shows bonding electron pairs as Lines and any nonbonding electrons as dots.
A chemical bond is holds atoms collectively in molecules. Bonds get up from the electrostatic forces between definitely charged atomic nuclei and negatively charged electrons.
Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis image consists of an elemental image surrounded by way of one dot for each of its valence electrons: parent 1 suggests the Lewis symbols for the factors of the 0.33 length of the periodic table.
Lone pairs are discovered in the outermost electron shell of atoms. They may be diagnosed with the aid of using a Lewis shape. Electron pairs are therefore taken into consideration lone pairs if two electrons are paired however aren't utilized in chemical bonding.
It is representation of the valence shell electrons in a molecule. it's far used to expose how the electrons are arranged round individual atoms in a molecule. Electrons are shown as dots or for bonding electrons as a line between the two atoms.

Answer:
Explanation:
Hello!
In this case, for such calorimetry problem, we can notice that the combustion of the compound releases the heat which causes the increase of the temperature by 11.95 °C, it means that we can write:
In such a way, we can compute the total released heat due to the combustion considering the calorimeter specific heat and the temperature raise:
Next, we compute the molar heat of combustion of the compound by dividing by the moles, considering 1.400 g were combusted:
Thus, we obtain:

The following types of bonds exists between the listed atoms;
- Si and O - polar covalent
- O and O - Covalent
- C and H - Covalent
- Li and F - ionic
- Ba and S - ionic
<h3>What is a polar covalent bonds?</h3>
A bond is polar covalent when the electronegativity difference between the bonding atoms is above that found in a nonpolar covalent bond. Now we shall see the types of bonds between these atoms.
