Answer:
The main difference between distillation and fractional distillation are:Simple distillation separate liquid with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquid with closer boiling point.

Step 1;write the equation for reaction
the equation for reaction is as follows
NaOH + H3PO4 ---> Na2 PO4 + H2o
then calculate the moles of H3PO4 used
that is 34.55 x1.500/1000= 0.052 moles
by use of mole ratio between NaOH to H3Po4 which is 1:1 the moles of NaOh= 0.052 moles
volume of NaOh is= moles of NaOH/ molarity
that is 0.052 /1.420=0.03662 L
in Ml = 0.03662 x1000=36.62 Ml
I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.
The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

I’m pretty sure it’s a acid but don’t trust me
