WebCambridge International AS and A Level Chemistry builds on the skills acquired at Cambridge IGCSE (or equivalent) level. The syllabus includes the main theoretical concepts which are fundamental to the subject, some current applications of chemistry, and a strong emphasis on advanced practical skills. WebReforming is a key step of the XTL process to produce syngas (CO and H 2 ). Syngas can be synthesized using three processes: steam reforming (SR), CO 2 reforming (dry reforming), and oxy-methane reforming (partial oxidation).
Webbonds and chemical side bonds. Breaking and reforming these side bonds allow us to rearrange the wave pattern of the hair. Physical side bonds can be broken using heat and water and reform when the hair dries and/or cools. However, this article is about perming and relaxing and the scientific processes that occur.
