Is conductivity a physical property or a chemical property? Explain. Does solid NaCl conduct electricity? Explain why or why not. What is the name of the salt? Zn(C_2H_3O_2)_2 How does electrolyte conductivity affect corrosion rate?
On a molecular level, compression stress forces atoms of malleable metals to roll over each other into new positions without breaking their metallic bond. When a large amount of stress is put on a malleable metal, the atoms roll over each other and permanently stay in their new position. Exam...
What is metal and its property? Metals arelustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). ... Ducti...
Is the freezing point of alcohol an intensive or extensive property? Explain. In general, metallic solids are ductile and malleable, whereas ionic salts are brittle and shatter readily (although they are hard). Explain this observation. Is conductivity a physical property or a chemical property?
Which metal is both malleable ductile? The metalslead and tinare both malleable and ductile ,biit their ' malleability, or spreading-out property, is much greater than ! Are alkali metals soft or hard? The alkali metals are solids at room temperature (except for hydrogen), but have fairly ...
25. Are the following propertiescharacteristics of ionic, covalent, or metallic bonding? a.Thesebonds are formed by delocalized electrons in an “electronsea.” b.Thesebonds involve a transfer of electrons. c.Substancescontaining these bonds are malleable and have very high meltingpoints. d.Su...
acid-base reaction. When a species is either protonated or depronated, its mass and charge change, plus its chemical properties are altered. For example, protonation may change the optical properties, hydrophobicity, or reactivity of a substance. Protonation is usually a reversible chemical reaction...
The gold is malleable and one or two pure gold pieces of gold leaf can be covered with nine square meters of gold leaf. The gold leaf is transparent, when the sunlight passes, can present green light. 50 grams of pure gold can draw up to 8, 000 meters, more than the hair. (6. ...
How is called an element that lacks most of the properties of a metal, is not shiny, does not conduct electricity or heat well, is not malleable? What possible atmospheric pollutants are produced by the refining of iron and copper?
The halogens are a group of chemical elements that are characterized by having an outer shell that is missing one electron to attain noble gas electron configuration. They are often colored in appearance.Answer and Explanation: Chlorine is not ductile and malleable. This is because chlorine is a...
