4D gas geological research on coal seam with gas hazard potential

gas 4dClass-leading multi-gas sensing solutions that can be seamlessly integrated with UAV platforms. These solutions sense up to 9 gases at a time and display their 3-D distributions in real-time,Diketahui reaksi: 2A + 3B + 2C → 4D Pada akhir reaksi gas:, terdapat 2,5 mol A; 1 mol C dan 2 mol D. Semua D adalah hasil reaksi, maka hitunglah
