You can smell the chemical changes, too.As they go up into your nose, especially when you forget about your sauce and it doesn't just cook but burns and becomes black and has a really bad flavor.You can't make it better, either, because once chemicals change, they can't be changed back again. 刷素养 返回目录 1.What does the underlined word “they” in Paragraph 2 refer to?( ) C A.Chemistry.
