Answer:
V = 2.75 L
Explanation:
Given that,
Mass of liquid glycerol, m = 3470 g
The density of liquid glycerol, d = 1.26 g/cm³
We need to find the volume of liquid glycerol.
We know that,
Density=mass/volume
We know that, 1 cm³ = 0.001 L
V = 2.75 L
So, the volume of liquid glycerol is 2.75 L.
Melting points and boiling points of molecular compound are usually lower than ionic compounds. This is so as only a small amount of energy is required to overcome the weak intermolecular forces of attraction (Van de Waals forces) thus having lower m.p. and b.p.
Ionic compounds require a large amount of energy to overcome the strong electrostatic forces of attraction between the ions, hence having higher mp and bp

Answer:
E° = -1.66 V
Explanation:
The standard reduction potential is also known as the standard electrode potentials and it tries to find the probability that an element will be reduced or undergo reduction.
From activation series online showing the standard reduction potentials for half cells, the standard reduction potential of Al3+ (aq) + 3e- -> Al(s) is;
E° = -1.66 V
