If you mean what I said , the particles in a solid vibrate in place.
Answer:
true
Explanation:
I'm not sure why cause I dont know how to explain but it's TRUE
Covalent bonds are formed between atoms which have
<span>- unsatisfied valency </span>
<span>- no inert gas electronic configuration </span>
<span>- These are directional bonds </span>
<span>- formed by sharing of electrons </span>
<span>Intermolecular forces </span>
<span>- much weaker than covalent bond </span>
<span>- These are not directional (except Hydrogen bonds) </span>
<span>- These are more electrostatic in nature </span>
<span>- exist between stable molecules </span>
<span>- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole </span>
Answer:-A. It is less than 890 kJ/mol because the amount of energy required to break bonds is less than the amount of energy released in forming bonds.
Explanation: Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and
for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
In the formation of new bonds more energy is released than is required to break the existing bonds, heat is released.
In the formation of bonds less energy is released than is required to break the existing bonds, heat is absorbed.
