Typical hydrogenation reactions include the reaction of hydrogen and nitrogen to form ammonia and the reaction of hydrogen and carbon monoxide to form methanol or hydrocarbons, depending on the choice of catalyst.
The GMAT exam consists of four sections: An analytical writing assessment, integrated reasoning, the quantitative section, and the verbal section. Total testing time is three and a half hours, but test takers should plan for a total time of approximately four hours, with breaks.
The total GMAT score ranges from 200 to 800 and measures performance on the quantitative and verbal sections together (performance on the AWA and IR sections do not count toward the total score, those sections are scored separately). Scores are given in increments of 10 (e.g. 540, 550, 560, 570, etc.).
