Answer:
Because of the presence of lone pairs in nitrogen it further adds to its reactivity. Hence nitrogen is more electronegative than chlorine. ... Chlorine is less reactive than nitrogen in other words nitrogen is more reactive than chlorine

Answer:
photosynthesis.
The green disks in Elodea plant cell under a microscope represent specialized plant cell organelles, known as chloroplasts. Chloroplasts are double-membrane bound cell organelles that contain green pigments or chlorophyll molecules.
These pigments trap the energy from solar light, which is used by the plants for the process of photosynthesis to make their food.
The balanced equation for the above reaction is as follows;
2H₂ + O₂ --> 2H₂O
stoichiometry of O₂ to H₂O is 1:2
number of O₂ moles reacted - 40.3 g / 32 g/mol = 1.26 mol
according to molar ratio
number of water moles produced = 2 x number of O₂ moles reacted
number of water moles formed - 1.26 x 2 = 2.52 mol
mass of water produced = 2.52 mol x 18 g/mol = 45.4 g
45.4 g of water produced
