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.
B. Mg2+(aq) C. Cl-(aq) D. Zn(s) explanation. The best reducing agent is the compound that is most favorably oxidized. According to the table, Mg2+(aq) is an oxidizing agent, because it has no electrons to lose and can gain two electrons to form the neutral metal.
