РТ по химии 2 этап | 2023-2024 | Полный разбор| Вариант 2

I was filming the video in a hurry, so I made a mistake in solving problem B19, calculating the chemical quantity incorrectly 🤦🏻‍♀️ The whole algorithm is correct! The correct solution is as follows: n(HNO₃)=132.3 kg : 63 g/mol = 2.1 kmol n(N₂)=2.1 kmol : (2*0.84) = 1.25 kmol V(N₂)=1.25 kmol * 22.4 dm³/mol = 28 m³ Option 1 –    • РТ по химии 2 этап | 2023-2024 | Полный ра...   I would be grateful for distributing this video, as your activity motivates me to film even more useful material.
