Answer:
Respiration process
Explanation:
Respiration is simply defined as the biochemical process where the body cells derive their energy from the combination of O₂ and food molecules, and in return liberates CO₂, along with some amount of H₂O and energy. This process elaborates on how the tissue cells help in shifting the O₂ from the exterior air into the cells and in return allows the CO₂ to be released outside.
This process is highly essential for an organism to survive. An organism cannot survive without carrying out this process.
The branch of science that deals with the identification of the substances of which matter is composed

Answer:
2 M.
Explanation:
I mole of NaCl reacts with 1 mole of HCl ( from the equation).
2 Liters of 5 molar contains 2 * 5 = 10 moles of NaCl so this will neutralise 10 moles of HCl.
So the concentration of 5 liters of HCl must be 10/5 = 2M.
