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.。
Iron is a metallic element with the chemical symbol Fe, and is one of the most prolific and commonly occurring mineral substances on Earth. Scientists estimate that is found in approximately 5% of the planet’s crust, and exists in its core, too. Iron turns to iron oxide when it comes in...
Iron is a redox-active essential element in almost all life, being involved in oxygen transport and electron transport in the mitochondrial electron transport chain (ETC) and DNA and protein synthesis. The effects of hinokitiol as an iron chelator can explain the inhibition of cell proliferation ...
Iron is a brittle, hard substance, classified as a metal inGroup 8 on the Periodic Table of the Elements. The most abundant of all metals, its pure form rapidly corrodes from exposure to moist air and high temperatures. Iron is also the fourth most common element in Earth's crust by we...
What is the state of matter for iron? What is Fe on the periodic table? What is the classification of levothyroxine? Is iron a metal, nonmetal or metalloid? Are the chemical element iron and the vitamin iron the same? What is the classification of sodium chloride?
Are the chemical element iron and the vitamin iron the same? The metal atoms in iron are held together by What are some features of a homogeneous substance? Two metals, A and B, are melted and mixed together to form an alloy and then allowed to solidify. This mixture is said to be a...
Tungsten is a refractory metal with the highest melting point and high temperature strength. It is mainly used in rocket propeller nozzles, armor-piercing bullets, super-hard drill bits, molds, etc., and is also commonly used as an additive element in refractory metal alloys. ...
Iron power inductor: Another core that can be used in a variety of types of inductor is iron oxide. Like ferrite, this provides a considerable increase in the permeability, thereby enabling much higher inductance coils or inductors to be manufactured in a small space. Different...
A photosensitive element, and a process for forming a high density photo mode image with it, is disclosed comprising a support, an image forming layer comprising an image forming substance, preferably carbon black, a photopolymerisable layer and a cover sheet. Optionally a release layer can be ...
