determine the amount of heat (in kJ) given off when 2.26 x 10^4 g of NO2 is produced according to the following equation: 2NO(g) + O2(g) --> 2NO2(g) and delta H= -114.6 kJ/mol 答案 -114.6 kJ * 491 moles/2 = -2.81 x 10^4 kJ 我覺得最後要除2...後面解答也是除2 可是今天老師他解答寫不用除2 問了之後解釋我還是搞不太懂... 到底要不要除於2??? 感謝解答 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 58.114.205.226 ※ 編輯: Purlas 來自: 58.114.205.226 (12/06 22:07)
