Answer: 8855 Joules energy is released when 115 g of
changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of
= 77 J/g
Mass of
given = 115 gram
Heat released when 1 g of
is freezed = 77 J
Thus Heat released when 115 g of
is freezed =
Thus 8855 Joules energy is released when 115 g of
changes from a liquid to a solid at its freezing point.
Answer:

Electron, Neutron, Atom, Molecule, Nucleus
Explanation:
sorry if it's not right
C.
This is also the only change by which crystals may be produced.
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
