descreening. Definition: Process in image processing of avoiding or removing moirÃ© effects in images due to scanning of photomechanically reproduced photographs or the capture of subjects with fine, regular pattern e.g. weave of jacket. * May take place during image capture or in post-processing. Why is it never straightforward?
In the above reaction between hydrogen and oxygen gases, oxygen is the oxidizing agent. Oxygen is a good oxidizer in reactions. Further, hydrogen peroxide, sulfuric acid, nitric acid, halogens, permanganate compounds, and Tollenâs reagent are some of the common oxidizing agents. Reducing Agent.
Note: C12 is the oxidation agent; it oxidizad Fe from oxidation state of zero to +2. The Fe is the reducing. agent; it reduced the oxidation number of chlorine from 0 to -1. Also, note that the reducing agent (Fe) was oxidized and the oxidizing agent (C12) was reduced.
