Answer:
Rutherford's atomic model explained how the electrons surrounded the nucleus of protons and neutrons. His model showed how J. J. Thomson's Plum Pudding model was incorrect.
Prokaryotes are usually unicellular - and so would not have tissue, organs or organ systems.Some prokaryotes are multicellular, and you could potentially say that they are a tissue (many similar cells working together to perform a task). However, no prokaryotes have organs or organ systems.
Answer:
118.75°C is the boiling point of a solution.
Explanation:
Mass of the solute that is barbiturates = 42.5 g
Molar mass of a solute = 184.2 g/mol
Moles of solute = 
Mass of the solvent that acetic acid = 825 g = 0.825 kg

Molality of the solution (m):

Elevation in boiling point is given as:

i = 1 (organic compound)


= Boiling temperature of solution.
T = boiling temperature of solvent that is acetic acid=117.9°C


118.75°C is the boiling point of a solution.
Answer:
In pair NaF and H2O both compounds exibit predominantly ionic bonding.
