反应 的K=0.400,则反应2NO(g)+O2(g)=2NO2(g)的K1应为( )。
At 0400 your vessel is dead in the water and in heavy fog. Your loran set fixes your position at LAT 41°12.1’N,LONG 72°43.5’W. Bottom samples are taken and indicate a composition of soft mud and shell. Your fathometer reads 40 feet. If the vessel draws 9 feet of water,which of the following is TRUE?()
