सिमेंटची निर्मिती ही खालीलपैकी कुठल्या घटकांपासून झालेली आहे ? / The composition of cement is :
Cement is primarily composed of calcium oxide (CaO), silicon dioxide (SiO2), and aluminium oxide (Al2O3).
N₂ + 3H₂ ⇌ 2NH₃ + Heat लि चॅटलीअर चे तत्व असे सुचित करते की ____________ असेल तर वरील रासायनिक अभिक्रियेत जास्तीत जास्त अमोनिया वायु तयार होईल. / N₂ + 3H₂ ⇌ 2NH₃ + Heat The Le Chatelier's principle suggests that ____________ are required to drive the reaction to the right and thus form NH₃.
According to Le Chatelier's principle, since the formation of ammonia is exothermic (releases heat) and decreases the number of moles of gas, high pressure and low temperature favor the forward reaction to maximize yield.
