The answer & explanation for this question is given in the attachment below.
The net ionic equation of borax hydrolysis would be:
<span>Na2B4O7 + 7H2O-----------------> 2 NaOH + 4 H3BO3
</span>
Wherein 2 moles of sodium hydroxide and 4 moles of boric acid are produced by the hydrolysis.

Explanation:
According to Charle's law, at constant pressure the volume of an ideal gas is directly proportional to the temperature.
That is, 
Hence, it is given that 
is 3.50 liters, 
is 20 degree celsius, and 
is 100 degree celsius.
Therefore, calculate 
as follows.
= 17.5 liter
Thus, we can conclude that volume of gas required at 100 degree celsius is 17.5 liter.
Entropy Change is calculated by (Energy transferred) / (Temperature in kelvin)
deltaS = Q / T
Q = (mass)(latent heat of fusion)
Q = m(hfusion)
Q = (500g)(333J/g) = 166,500J
T(K) = 32 + 273.15 = 305.15K
deltaS = 166,500J / 305.15K
deltaS = 545.63 J/K
No, because an atom consists of two main parts and three subatomic
particles, protons, neutrons, and electrons. Each one is smaller than an atom, therefore they are subatomic particles. An atom only requires protons and electrons to be an atom - e.g. Hydrogen has 1 proton and 1 electron. Neutrons do not effect the overall charge of the atom, and only increase the atomic mass.
