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,
Answer:
Explanation:
Simply
Coal has two valent electrons, so there is 2 in 2p orbital
B) decreasing the reactants particle size
It’s probs a because 75-25 is 30 so it’s probs 30°C
Answer:
B. Intermolecular forces are hard to overcome
Explanation:
A high boiling point indicates greater inter molecular forces between the molecules of the substance. Inter molecular forces is the force of attraction between the molecules of the substance, which has to be overcome or broken before the substance boils. Example, when water boils, the water molecule (H₂O) will be broken into hydrogen molecule and oxygen molecule.
Therefore, a high boiling point temperature indicates that intermolecular forces of the substance are hard to overcome.
