Answer:
for the given reaction is -2486.3 kJ
Explanation:
The given equation can be written as a combination of the following equation:
;

Wind results due to difference in air pressure of air masses. Due to difference in pressure of two air masses, low pressure zone is created by lifting of one the air mass above the other as the movement of air takes place from higher pressure area to lower pressure area. This causes different wind speed in different areas. The direction of wind depends on its origin for example, a northerly wind always moves from north to south direction.
Hi,
the answer should be the last one, ‘neither accurate nor precise’.
The values are quite different from one another and not close to the actual value.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
Answer:
10.32 moles of ammonia NH₃
Explanation:
From the question given above, the following data were obtained:
Number of molecules = 6.21×10²⁴ molecules
Number of mole of NH₃ =?
The number of mole of NH₃ can be obtained as follow:
From Avogadro's hypothesis,
6.02×10²³ molecules = 1 mole
Therefore,
6.21×10²⁴ molecules = 6.21×10²⁴ / 6.02×10²³
6.21×10²⁴ molecules = 10.32 moles
Thus, 6.21×10²⁴ molecules contains 10.32 moles of ammonia NH₃
