Which is an intermediate in this reaction mechanism: step 1: h2o2 + i- → h2o + oi- step 2: h2o2 + oi- → h2o + o2 + i- a. h2o2 b. i- c. oi- d. o2

Explanation:

An intermediate is defined as species which are produced in one step of a reaction and consumed in the other. It is important not to confuse an intermediate with a catalyst. Catalyst is consumed in one reaction and produced in one of the subsequent reactions.

Given the mechanism of this reaction, in the first step we produce . Notice that the same species, , is produced in the subsequent step 2. In this case, is the intermediate, as it follows the definition of an intermediate.

For your own information, iodide anion is a catalyst, as it's consumed in step 1 and reproduced in step 2.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
