As an example, consider rust formation. When rust forms, the metal iron reacts with oxygen in the air to form a new compound, iron oxide (rust). This chemical reaction may be expressed by the following unbalanced chemical equation, which may be written either using words or using the chemi...
When iron rusts, it is a chemical change. What happens during this process? A. The color remains the same. B. No chemical reaction occurs. C. A new substance is formed. D. The mass of iron decreases. 相关知识点: 试题来源: 解析 C。铁生锈是化学变化,在这个过程中会形成新物质。A ...
What happens when chemical bonds break and new bonds form? An atom loses one of its neutrons. What changes about the atom? What is the most dangerous chemical reaction? How do you draw chemical reactions? Is rust the result of a chemical reaction?
Oxidation is a chemical reaction involving the loss of electrons, affecting various substances, while rust is a specific type of oxidation that occurs on iron or steel, forming iron oxide.
What is photosynthesis? A. A reaction that produces rust. B. A process by which plants make food. C. A reaction that only happens in our bodies. D. A chemical reaction when something burns. 相关知识点: 试题来源: 解析 B。原因:文中提到“Chemical reactions are also involved in ...
What are the basic chemical reactions? Is mendelevium malleable? What are redox half reactions? What type of chemical reaction is rust? Is mendelevium brittle? How does beryllium react with water? What is the outermost energy level of mendelevium?
What is the chemical reaction of rusting of iron? Rusting isan oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur...
What Is Rust? Rust is a form of corrosion that primarily affects iron and its alloys, such as steel. The chemical reaction between iron, oxygen, and water forms iron oxide, commonly known as rust. More specifically, it’s when elements, like iron, easily lose electrons, and an element su...
Corrosion is a broad term describing the chemical or electrochemical reaction between a material, usually metal, and its environment, leading to the material's deterioration. Rust, on the other hand, refers specifically to the red or orange coating that forms on the surface of iron and its allo...
Rust occurs when iron water and oxygen mix together. It's normally called oxidation. Rust is a chemical reaction. Byanon971278— On Sep 24, 2014 I know what rust is but why does it form? Can metals that are not alloys of iron rust?
