Answer: Speed has the dimensions of distance divided by time.
Explanation:
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.
SI unit: m/s, m s−1
Common symbols: v
Dimension: L T−1
Answer:
The *intramolecular* bonding between the Hydrogen and Oxygen atoms are called Covalent Bonds.
Covalent bonds are strong electrostatic attractions between 2 positively charged nuclei and a shared pair of electrons.
The *intermolecular bonding* of water molecules is called hydrogen bonding as well as instantaneous - induced dipole interaction.
Instantaneous-induced dipoles is where 2 water molecules interact. The results in negative electron clouds repelling each other resulting in a region of positive charge - the molecules are said to have an induced positive charge.
This water molecule with an induced positive charge then attracts electrons from a neighbouring water molecules - resulting in an instantaneous negative dipole.
These dipoles are fleeting/temporary and are the weakest intermolecular bonds.
Hydrogen bonding is a result of the 2 line pair of electrons in Oxygen atom of the water moelcule. These electrons are attracted to extremely electronegative (electronegativity :ability of an atom to attract a bonding pair of electrons) elements such as Oxygen from a neighbouring water molecule resulting in what is known as hydrogen bonding,
The name of the acid whose formula is Hi is Hydrogen iodide
