What is a Lewis Structure?
A Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs this is a CO32− model
Why covalent-network substances are insoluble in all common solvents?
Covalent-network substances have strong covalent bonds that hold their atoms together in a three-dimensional network structure. This network structure makes it difficult for common solvents to break the bonds and dissolve the substance, leading to their insolubility in most solvents.
How many bonds can sulfur form in a Lewis structure?
Sulfur can form a maximum of six bonds in a Lewis structure.
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
SO2 is the substance that has polar covalent bonds. This is because sulfur and oxygen have different electronegativities, resulting in an uneven sharing of electrons in the covalent bonds within the molecule.
What formula represents a substance that contains covalent bonds?
A molecular formula represents a substance that contains covalent bonds. This formula shows the types and numbers of atoms present in a molecule, such as H2O for water, which consists of covalent bonds between hydrogen and oxygen atoms.
How many single covalent bonds down at is the Lewis dot structure for hydrogen bromide?
The Lewis dot structure for hydrogen bromide (HBr) consists of a single covalent bond between the hydrogen atom and the bromine atom. So, there is one single covalent bond in the Lewis dot structure of HBr.

How many bonds should be drawn in the Lewis-dot structure for BH3?
In the Lewis dot structure for BH3, there should be 3 bonds drawn. Each hydrogen atom forms a single covalent bond with the boron atom. Boron has three valence electrons, so it can form three bonds with the hydrogen atoms.
What does humidity do to the hair structure?
The cells in hair are held together by covalent bonds and covalent bonds are affected by water.

What is the ionic bonding of diamond?
Diamond does not contain ionic bonds. It is composed of carbon atoms arranged in a tetrahedral lattice structure held together by strong covalent bonds. Each carbon atom shares electrons with four neighboring carbon atoms, creating a network of covalent bonds throughout the entire crystal structure.
What substance forms when bonds between atoms are broken?
Covalent bonds are the easiest to break, since they are the easiest to make. But no substance is made when bonds break.
What is the Lewis structure of NCS and how does it represent the bonding arrangement of the atoms in the molecule?
The Lewis structure of NCS shows nitrogen bonded to carbon and sulfur with single bonds. The nitrogen has a lone pair of electrons. This arrangement represents a linear molecule with each atom following the octet rule, forming stable covalent bonds.
How many single and double covalent bonds does a carbon atom have in a carbon dioxide molecule?
Two covalent bonds attach both Oxygen atoms to the Carbon atom. You should have figured that out using the Lewis structure.
