Answer:

57.792 kJ

Explanation:

Molar enthalpy of fusion of the substance is defined as the energy required to convert the substance in solid state, at its melting point to liquid state at constant pressure and no change in temperature.

For example the energy required to convert 1 mole of water (ice) at 0°C to 1 mole of water (liquid) at 0°C is 6.02 kJ/mol.

<u>Thus, thermal energy required to convert 9.60 moles of ice is 6.02×9.60 kJ = 57.792 kJ</u>

The  thermal energy  needed to  completely  melt  9.60  mole  of ice  at  0.0 C  is    57.8   Kj

        Explanation
ice  melt  to  form   water

The molar  heat of fusion  for   water  is  6.02  Kj/mol
Thermal energy =  moles  x  molar  heat  of  fussion  for water

=9.6  mol  x6.02 kj/mol =57.8  Kj

Which is more stable: neutral chlorine atoms or chlorine ions? Why?​
lubasha [3.4K]

Answer:

When we say "chlorine wants to gain one electron", we speak of the radical atom. Chlorine as a free radical, Cl⋅ , is the chlorine atom that we say has 7 valence electrons and wants its 8th to form an octet. So, Cl⋅ , chlorine radical, is less stable, and Cl− , chlorine ion, is more stable
