In the reaction between iron and oxygen to form iron oxide, which element is reduced? A. Iron B. Oxygen C. Both iron and oxygen D. Neither iron nor oxygen 相关知识点: 试题来源: 解析 B。原因:In the reaction of iron and oxygen, oxygen is reduced as it gains electrons from iron.。
Redox Reaction: The reaction in which one element is oxidized and another one is reduced simultaneous is known as redox reaction. For example: formation of water molecules from hydrogen gas and oxygen gas (hydrogen atom is oxidized and Oxygen atom is redu...

A method for supplying a viscous substance includes providing a viscous substance capable of changing its adhesiveness corresponding to the polarity of a voltage to be applied thereto; supplying the viscous substance between a pair of electrodes; and applying a pulse voltage between the pair of ...
Consider the following unbalanced redox reaction: MnO_4(aq) + SbH_3(aq) to MnO_2(s) + Sb(s) What is the reducing agent in the reaction?For the following redox reactions, determine which element is being reduced and which is being oxidized. \ 3C_2H_6O(aq) ...
(high).With this trend,we will hopefully see a rise in the number of hawksbill sea turtles worldwide.答案(1)length.考查名词。句意:它们通常长度在70到90厘米之间,重量在45到70公斤之间。根据空前的介词in可知,空出需要名词,long为形容词,其名词形式为length"长度",为不可数名词,故...
In this sequence system, the case was considered where a diad was constituted of 'a' elements only, i.e., ('aa'), solely corresponded to an element of other two- element set, S= {s, t}. This is a general expression for a bi-component copolymer sequence in which one monomer unit ...
Heparin binding epidermal growth factor-like growth factor (HB-EGF) is an angiogenic factor mediating radial migration of the developing forebrain, while vascular endothelial growth factor (VEGF) is known to influence rostral migratory stream in rodents.
A primary radiator has a dielectric feeder at an open end of a waveguide in which the total length of the dielectric feeder is reduced. The dielectric feeder includes a holding portion forced into the
PURPOSE: A high-output variable optical attenuator using a fusion fiber coupler is provided to reduce the insertion loss and the manufacturing cost by using the fusion fiber coupler. CONSTITUTION: A high-output variable optical attenuator using a fusion fiber coupler includes a fusion optical coupler...
