The stable form of Nitrogen is N-14 and N-15.
- Nearly all proteins contain nitrogen, which is crucial for biochemical processes as well as industrial processes.
- Due to its capacity to form a triple bond with both itself and other elements, nitrogen forms strong bonds. As a result, nitrogen compounds contain a lot of energy. Little was known about nitrogen before one hundred years ago.
- More than 99 percent of all nitrogen found on Earth is found in the most abundant form of nitrogen, nitrogen-14. non-radioactive and stable, it is a substance.
- The most widely used form of nitrogen, 14, is used in biochemicals, biomedical research, food preservation, and agricultural practices.
- The second stable state of nitrogen is nitrogen-15. It is frequently employed in medical preservation and research.

Answer:
Have some attraction towards each other
Explanation:
Gases deviate from the ideal gas behavior because their molecules have forces of attraction between them. At high pressure, the molecules of gases are very close to each other so the molecular interactions start operating and these molecules do not strike the walls of the container with full impact.
Hope this helps :-)

Answer:- d) 42 kJ of heat is released and the reaction is exothermic.
Solution:- Heat of reaction is the summation of heats of products - reactants.
![\Delta H_r_x_n=\sum [products-reactants]](https://tex.z-dn.net/?f=%5CDelta%20H_r_x_n%3D%5Csum%20%5Bproducts-reactants%5D)
From given information, the energy contained by products is 352 kJ and the energy contained by reactants is 394 kJ. Let's plug in the values in the formula:
= [352 kJ - 394 kJ]
= -42 kJ
Heat of reaction is -42 kJ. The negative sign indicates the heat is released means the reaction is exothermic.
So, the correct option is the last one, 42 kJ of heat is released and the reaction is exothermic.
Explanation:
Photosynthesis is the process by which green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
It is expressed using the equation below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
reactants products
1. Compounds consumed are carbon dioxide and water.
2. Product is glucose and oxygen.
3. Most organism obtain their nourishment directly and indirectly from photosynthetic activities.
Plants are the producers of food in the ecosystem. If the process of photosynthesis does not occur, there is no way other organisms will obtain their own nourishment.
