Explanation:

It is known that density is the amount of mass present in liter of solution or substance.

Mathematically,      Density = \frac{mass}{volume}

It is given that volume is 3.25 L and mass is 4.10 \times 10^{3} g. Hence, calculate the density of glycerol as follows.

                     Density = \frac{mass}{volume}

                                   = \frac{4.10 \times 10^{3} g}{3.25 L}

                                    = 1.26 \times 10^{3} g/L

As, 1 L = 1000 cm^{3}.

So,           1.26 \times 10^{3} g/L \times \frac{1000 cm^{3}}{1 L}

                 = 1260 \times 10^{6} g/cm^{3}    

Thus, we can conclude that the density of glycerol is 1260 \times 10^{6} g/cm^{3}.

When pellets of NaOH(s) are added to a flask of water, it is observed that the temperature of the water increases as the pellets
Nataly [62]

Answer: It is an exothermic process because heat energy is absorbed by the water as the NaOH(s) dissolves in it.

Explanation:

Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant are less than the energy of product. In endothermic reaction, the change in enthalpy is, positive

Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product. In exothermic reaction, the change in enthalpy is, negative.

Thus as energy is absorbed by water, which has been released by NaOH, the process is exothermic.

vitfil [10]
[Co(CN)₆]³⁻ → Yellow
[Co(NH₃)₆]³⁺ → Orange
[CoF₆]³⁻ → Blue
Explanation:
- All the given compounds have octahedral geometry but the ligand in each are different with the same metal ion.

- Ligands strength order:     CN⁻ > NH₃ > F⁻ 

- The ligand CN will act as a strong field ligand so that the splitting is maximum when compared to NH₃ and F⁻

- If the splitting is more, the energy required for transition is more, and the wavelength is inversely proportional to energy.

- So CN complex will absorb at lower wavelength (yellow color)
