What are the properties and uses of silver?
It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
What is chemical properties and physical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
Which is chemical property?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
Is the luster of silver a chemical property?
Metallic luster is a physical property because it is an observable characteristic of metals. Even there are changes in the mass of the metal, it would still have the same appearance; hence, it does not affect its identity.
Which of the following is not a physical property of silver?
Answer : (d) brittleness.

What are two chemical properties examples?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are 6 physical properties?
Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
What are physical and chemical properties give an example of each?
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.
How many chemical properties are there?
What are 10 chemical properties examples? 10 examples of chemical properties include flammability, toxicity, solubility, heat from combustion, radioactivity, types of chemical bonds formed, coordination number, oxidization states, and acidity or basicity.
Is silver tarnishing a physical or chemical property?
The only way we can observe tarnishing is by changing silver to this new substances, silver oxide which is commonly called tarnish. So it is a chemical property.
Is luster a physical or chemical property?
Luster is a physical property that describes how a mineral’s surface and structure interact with light. I.e., luster describes how a mineral reflects and refracts light.
When silver tarnishes is it a physical or chemical change?
When silver objects are exposed to pollutants normally found in air, they gradually become dull and discolored. This darkening of silver is called tarnishing. It occurs when silver undergoes a chemical reaction, classified as an oxidation reaction, with sulfur-containing substances.
What are 5 physical properties of gold?
- Gold conducts heat and electricity.
- Gold is ductile: It can be drawn out into the thinnest wire.
- Gold is highly reflective of heat and light.
- Gold is prized for its beauty.
- Gold is malleable, so it can be flattened into extremely thin sheets.

Does silver react with water?
Silver does not react with pure water. Is is stable in both water and air. Moreover, it is acid and base resistant, but it corrodes when it comes in contact with sulphur compounds. Under normal conditions silver is water insoluble.
What is special about silver?
Silver is the best electric conductor of the elements; all other elements are measured against it. It is the only element that scores 100% conductivity, with the next closest element being copper at 97%. 26. Silver is also the best thermal conductor of any metal but has the lowest contact resistance.
Is silver flammable?
Silver and most soluble silver compounds are not combustible. However, silver nitrate and certain other silver compounds are oxidizers and can increase the flammability of combustible materials.
