We have ΔG = ΔH – TΔS; by substituting ΔH = 19.07 kcal and ΔS = 90 cal/K, we get ΔG = 19.07 Kcal – 293(90 cal/K) = 19.07 Kcal – 26.37 Kcal = -7300 cal = -7.3 Kcal. The Gibbs free energy change is -7.3 Kcal.

Using the equation ΔG = ΔH – TΔS, where G is represented by the Gibbs free energy, H is represented by the change in enthalpy, T is represented by the temperature and S is represented by the entropy. ΔH = ΔG + TΔS = 3.4 kcal – 293 x 2.4 cal/K = 3.4 kcal.

The chemical equation for the conversion of oxygen to Ozone is 3/2O₂ → O₃. We have the equation, ΔG = – 2.303 RT log Kp.
So by substituting we get ΔG = – 2.303 x 8.314 J/K-mol x 293K x 2.47 x 10^-29 = 163000 J/mol = 163 kJ/mol.

A vector in a plane will be defined by the two governing axes, X and Y. Hence, any vector can be resolved in two independent directions. If it is resolved in any other direction, that component of it will be dependent on the existing independent directions.

The only acceleration in projectile motion is the acceleration due to gravity. If the maximum height of the projectile motion is not large, and can be neglected with respect to the radius of earth (which usually is the case), the acceleration due to gravity remains constant. Hence, the acceleration in projectile motion remains constant.

Circular motion is an example of motion in a plane. As a circle is a 2-dimensional entity, the body moving in a circle is also moving in a plane. Hence the motion can be termed as motion in a plane.

Frankia is a microbe that is capable of fixing nitrogen in non-leguminous plants such as Alnus. It also produces nodules in the roots of plant. It can freely live in soil but fixes nitrogen as a symbiont. Bacillus is a free living anaerobic nitrogen fixer. Beijernickia is an aerobic nitrogen fixer. Anabaena is a microbe among the cyanobacteria that is capable of nitrogen fixation.

Transaminase is the enzyme which catalyses the process of transamination. Nitrogenase is responsible for nitrogen fixation. Glutamate dehydrogenase has role in the process of reductive amination. Lipase is a linking enzyme and has no role to play in nitrogen metabolism.

Amides contain more nitrogen than amino acids. They are transported to other parts of the plant through xylem vessels. Phloem tissue has no function in relation to translocation of amides.

Carolous Linnaeus introduced the system of Binomial Nomenclature. Charles Darwin came up with the theory of evolution. Henry Cavendish is the one who discovered hydrogen. James Chadwick is the one who discovered neutron.
