To melt a solid, energy must be input into the solid to give the molecules high energy to disrupt the lattice bonds and change phase. To return the liquid to solid, the same amount of energy used in melting is required to be removed from the liquid, ideally. This is assuming there is no loss of energy in the process.
Answer:
Coefficients represents no of moles while subscripts represent no of atoms.
Answer:
hydrogen bonds are a type of a chemical bond that are with the molecules or we can say that it is a bond which connects atoms together to form a compound or a molecule. an example will be water. this bonding occurs between hydrogen and four other elements which are Oxygen, Fluorine, Nitrogen and Carbon.
Answer:
CO2 + H2O = C6H12O6 + O2
or
6CO2 + 6H2O = C6H12O6 + 6O2 if it need to be balanced
Answer
option (B) is right answer
