Do magnets rust in vinegar?
Acids (including dilute acids such as vinegar) are reducers- they will corrode metals. Vinegar may cause accelerated corrosion while (due to high water content) also oxidising (rusting) metals which are prone to oxidation. To accelerate the oxidation of metals, you require a stronger oxidising agent. However, using a dilute acid may enhance the oxidation process in metals which galvanise. Some metals do not 'rust' as they develop a protective oxide layer when exposed to oxidising agents, or metal parts which can rust may contain or be coated with such a metal - types of steel, for instance. An acid may corrode the galvanising layer or metal, allowing the more vulnerable metal to continue oxidation.
What is the oxidation number of XeO6?
If iXeO6 existed Xe would have the amazingly high oxidation number of +12! +8 is the "record" in XeO4
What has more resistance a nichrome wire or a copper wire?
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.
Is fuse wire characterized by high resistance and high melting point?
Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
Does S8 have a high oxidation number?
Oxidation number is a concept that refers to atoms not molecules. The oxidation number of S in S8 is zero. The oxidation number of an atom in the pure element is always 0. S8 is a form of sulfur, the most commonly encountered , there are many other forms (allotropes). The oxidation number of S in any of its allotrpes is zero.
Can you explain the Electroplating of nickel-cobalt - alloys?
Cobalt metal is used in electroplating because of its appearance, hardness, and resistance to oxidation. It is alloyed with iron, nickel and other metals to make Alnico, an alloy of unusual magnetic strength with many important uses. Stellite alloys, containing cobalt, chromium and tungsten, are used for high-speed, heavy-duty, high temperature cutting tools, and for dies in the metal.
What are the benefits of electroplating?
Electroplating is used for components and equipment in all fields of technology to: 1.protect the material against corrosion 2.improve the surface properties 3.achieve optimum decorative effects
Does a metal is high melting point but low resistance?

Why does copper have a low resistance?
Because it is a metal so has lots of free electrons which when connected to a circuit detach from the atoms and move around the circuit. This produces a high current, so resistance will be low as current is high.
For what purpose objects are electroplated?
Electroplating is the process of covering a surface with a metallic coating using electronic components. There are many reasons why electroplating is important, e.g. Electroplating creates a protective barrier by applying a thin, durable metal coating to reduce friction and prevent surface stains to protect the surface from friction and tears. The coating of a non-metallic surface with metallic changes the surface properties of an object. In doing so, the use of metal coatings is used to change the wear, corrosion protection, protection from corrosion and sometimes the aesthetics of an object. Electroplating makes cheap metals look like high quality metals. Several industries use a few electronic connections such as automobiles, aircraft, electronics, entertainment and agriculture. Types of electroplating. Mass metal or barrel (electronic connection) placing the part inside the barrel. This type of electroplating fastener is great for hardware and metal stamping and is expensive for coating large quantities of small parts. The plated part of the rack is attached to the metal rack. For large or complex parts, machined or fine threaded parts work effectively for quality purposes.
Properties of inconel material?
A nickel-chromium alloy with good oxidation resistance at high temperatures and resistance to chloride-ion stress-corrosion cracking, corrosion by high-purity water, and caustic corrosion. Used for furnace components, in chemical and food processing, in nuclear engineering, and for sparking electrodes.
What is the best metal to make a toilet with?
Stainless steel - Its comparitavly light, can be welded and has a high resistance to rusting and water damage.
What metals are used to make metal screws?
Metals are used for the production of screws as they are materials with high hardness and resistance to stress.
What is a conductor made from?
depends on what you are conducting but generally a metal is a universal conductor. if it conducts electricity well then it will conduct heat well. some metals are better than others and you can figure this out by resistance values of the type of metal. more resistance makes it a less efficient conductor. insulators have very high resistance.
What is high corrosion?
Chemical deterioration of a material (typically a metal) under very high temperature conditions. This non-galvanic form of corrosion can occur when a metal is subject to a high temperature atmosphere containing oxygen, sulfur or other compounds capable of oxidising (or assisting the oxidation of) the material concerned.
Why do spark plug wires have resistance?
All wires have a resistance, as does everything else in the universe. Conductors like metal and carbon generally have low resistances where as non conductors have a very high resistance. Think of it like friction, but electric.
Which element are used as an electric heater filament?
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
