My dream room. Wow, let's start with the interior I would like my room to have delicate pastel ocher wallpapers, on which I would hang posters of my favorite bands. My room must have a balcony with a table and two chairs. It will be decorated with different flowers and in the morning I will have a cup of coffee there. There will be a large round bed in my room, there will be a work table on the side, a dressing table next to it, a small table. Opposite the tables will be a wardrobe, vast and full of different and interesting outfits. There will be many plants in my room, and I will stretch a bright yellow garland across the ceiling. This is the room of my dreams
Если от молекулы этилена отнять еще два атома водорода, т. е. дегидрировать его, то получится еще более непредельное соединение — ацетилен, в молекуле которого имеется еще одна связь между углеродными атомами, т. е. сформируется тройная связь: H H.

Объяснение:
1) Дано:
V C2H6+C2H2 = 56 м3
φ С2H2 = 75 %
С2H6 + 3,5O2 = 2CO2 + 3H2O
C2H2 + 2.5 O2 =2 CO2 + H2O
n C2H2+C2H6 = 56000/22.4 = 2500 моль
n C2H2 = 2500*0.75 = 1875 моль
n C2H6 = 2500-1875 = 625 моль
n O2 = 1875*2.5 + 625*3,5 = 6875 моль
V O2 = 6875*22.4 =154 м3
2) Дано:
Q = 1300 кДж
V C2H2 = 30 м3
n C2H2 = 30000/22.4 = 1339.3 моль
Q = 1339.3*1300 = 1.7 МДж
