Автор ответа: Летов

Кол-во метана 33,6/22,4=1,5 моль. По уравнению:

CH4 + 2О2 = СО2 + 2Н2О +900 кДж

на 1 моль метана выделяется 900 кДж тепла, тогда на 1,5 моля: 1,5*900=1350 кДж

There was only one goal - to prevent the enemy from reaching Moscow ... I measured the distance with a compass, we were 30 kilometers from Moscow. Moscow was under bombardment.
... It is a rainy day. We manage to stop the Germans on the first day. On the second day in Kryukovo, there is a six-hour street fight, on the third day - a 12-hour street fight is already in the center. Every other day, street fighting continues for 18 hours.
