Answer:
Single bond between two carbon atoms.
Explanation:
Let us look at the structure of a hexagon for representation of cyclohexane.
Cyclohexane has six carbons and thus we can place each carbon at the vertices of the hexagon. Now the bond joining each adjacent carbon atoms will be shown by the each side of the hexagon.
The hydrogen atoms are not shown in the structure.
Answer:
Single bond between two carbon atoms.

Explanation:
Microwave background is basically electromagnetic radiation, but it's the remanent from earlier periods of the universe, they are the oldest electromagnetic wave in the Universe. Also, Hubble's Law says that the Universe faster galaxies are those are further away, because they belong to the first period of the explosion.
Answer:
Explanation:
The partial negative charge in a water molecule occurs because of differences in electronegativity between the atoms involved. A water molecule (H2O) consists of two hydrogen atoms and one oxygen atom. Oxygen is significantly more electronegative than hydrogen, which means it has a stronger attraction for electrons.
In a covalent bond between hydrogen and oxygen, such as in a water molecule, electrons are shared between the two atoms. However, because oxygen is more electronegative, it pulls the shared electrons closer to itself, creating an uneven distribution of electron density. This results in the oxygen atom having a partial negative charge (δ-) and the hydrogen atoms having partial positive charges (δ+).
The electronegativity difference between hydrogen and oxygen causes the electrons in the covalent bonds to spend more time around the oxygen atom, making it partially negatively charged. This partial negative charge on the oxygen atom and the partial positive charges on the hydrogen atoms give water its polar nature. This polarity plays a crucial role in various chemical and physical properties of water, such as its ability to form hydrogen bonds, its high surface tension, and its unique solvent properties.
Answer:
The correct answer is non-metals.
Explanation:
In the covalent bond, the two non-metallic atoms share one or more electrons, i.e., they bind through their electrons in the last orbital. Covalent bonds normally occur between atoms with similar and elevated electronegativity, from which removing the electron completely requires a lot of energy.
Have a nice day!
