Answer:

Enthalpy, Entropy, Spontaneity, Gibbs free energy, saturated solution

Explanation:

Enthalpy is defined as the heat released or the heat absorbed during the process at a constant pressure which is equal to the Enthalpy shift. Enthalpy is also called as heat content and it is the sum total of internal energy and the product of the volume and pressure of a system.

Entropy is defined as the measure of randomness of a system or the disorder of the system.

Spontaneity is defined as the condition of being spontaneous. It is the condition where a reaction takes place without any help from outside.

Gibbs free energy is defined as the energy that is used to quantify the maximum work done in a thermodynamic system at constant temperature and pressure. It is the also known as the Gibbs energy or function.

Saturated solution is defined as the solution where the maximum amount of the dissolved solute is present in the solvent. In case of a saturated solution, the extra solute does not dissolve. In order words, it is a solution where no more solute can dissolved in solvent.

Reptile [31]

Answer:

Ammonia, urea, uric acid

Explanation:

The given compounds are:-

Urea which has a molecular formula of CH_4N_2O and has 2 atoms of nitrogen per molecule.

Ammonia which has a molecular formula of NH_3 and has 1 atom of nitrogen per molecule.

Uric acid which has a molecular formula of C_5H_4N_4O_3 and has 4 atoms of nitrogen per molecule.

Thus,

The order from least to most nitrogen is:-

Given the information that nitrogen atoms are larger than hydrogen atoms,which of the models best represent ammonia?(NH3)
Ray Of Light [21]

Answer:

<em>The correct option is the structure in the option D. </em>

Explanation:

Ammonia contains a single nitrogen atom bonded to three hydrogen atoms.

The structure present in option A shows a single nitrogen atom bonded with a single hydrogen atom hence it is not correct.

The structure in option B shows a nitrogen atom bonded to four hydrogen atoms hence it is also not correct.

The structure in option C shows a nitrogen atom bonded to two hydrogen atoms hence it is also not correct.

The structure in option D shows a nitrogen atom bonded to three hydrogen atoms which is the correct structure of ammonia (NH3).
