Electroplating is the main use of this metal which has a high resistance to oxidation?
Chromium is widely used for electroplating. Chromium is a hard brittle metal that polishes well, has high resistance to heat and is highly resistant to tarnish.
What is A metal with an oxidation state of 3 used in cans?
Aluminum is a metal with an oxidation state of +3 and is commonly used in making cans for beverages and food products. Its properties make it suitable for this purpose due to its strength, light weight, and resistance to corrosion.
When a substance is undergoing oxidation does the oxidation number increase?
Yes, during oxidation, the oxidation number of the substance increases. This is because oxidation involves the loss of electrons, leading to an increase in the oxidation number.
Why platinum is used in platinum resistance thermometer experiment?
Platinum resistance thermometer requires a small current to pass through it to determine its resistance at different temperatures. Platinum has a linear resistance-temperature relationship; we can use this method to find the resistance at different temperatures.
What is the oxidation number of nitrosyl?
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
What is difference between corrosion resistance and oxidation resistance?
corrosion resistance is resistant against chemicals oxidation resisstance is restant against oxigen
What is a property in chemistry?
Examples: chemical reactivity, resistance to corrosion, flammability, oxidation, etc.
Electroplating is the main use of this metal which has a high resistance to oxidation?
Chromium is widely used for electroplating. Chromium is a hard brittle metal that polishes well, has high resistance to heat and is highly resistant to tarnish.
What is the electrical resistance of a penny?
The electrical resistance of a penny can vary based on its composition and condition, but a typical copper penny (post-1982) has a resistance of about 1 to 2 ohms. This value can change due to factors like oxidation, surface condition, and temperature. Generally, the resistance is low due to copper's excellent conductivity.
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 A metal with an oxidation state of 3 used in cans?
Aluminum is a metal with an oxidation state of +3 and is commonly used in making cans for beverages and food products. Its properties make it suitable for this purpose due to its strength, light weight, and resistance to corrosion.
What properties are needed for the heating element of an electric iron?
The heating element of an electric iron needs to have high electrical resistance, good heat conductivity, and resistance to oxidation. Additionally, it should be durable and able to reach and maintain high temperatures to effectively iron clothes.
What is considered a chemical properties of a substance?
Examples: - flammability - resistance to corrosion - resistance to thermal degradation - oxidation - reduction - apptitude for polymerization - chemilumiscence etc.
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.
When a substance is undergoing oxidation does the oxidation number increase?
Yes, during oxidation, the oxidation number of the substance increases. This is because oxidation involves the loss of electrons, leading to an increase in the oxidation number.
