Answer:
Polarity in chemistry referred to physical properties of compounds related to solubility, melting and boiling properties.
Polarity of black pepper can be seen when black pepper is sprinkled on water. The balck pepper float on water and get displaced if touched.
It means black pepper is non-polar and have no difference in electronegativity between bonded atoms. Black pepper is so light in weight and non-polar, the surface tension of water keep it floating in the water.
Use the formula for volume. V = lwh. Plug in the numbers for length,
width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the
volume of the block is 8.0 cm.

Answer:
<u>Reaction is called exergonic when ΔG is negative i.e. ΔG < 0</u>
Explanation:
The Gibbs free energy represents the spontaneity or feasibility of a given chemical reaction at constant pressure and temperature and is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in the Gibbs free energy
ΔS - change in the entropy
ΔH - change in the enthalpy
T - temperature
If the value of <u>ΔG for a chemical reaction is positive i.e. ΔG > 0</u>, then the given chemical reaction is said to be nonspontaneous. Such a reaction is called endergonic.
Whereas, if the <u>ΔG value for a chemical reaction is negative i.e. ΔG < 0</u>, then the given chemical reaction is said to be spontaneous. Such a reaction is called exergonic.
