Why equivalent conductance increase with dilution whereas specific conductance decrease?
the specific conductance of the electrolyte falls because of the no of current carring particles i.e. ions present per centimetercube of the soltion becomes less and less on dilution how ever increase in eqi bacause it is the product of specific conductance and rthe volume v of the sol contain 1 gm of eq electrolyte or one mole of the elecrtrolute that's why .............................................
What is a 'poor metal'?

When two dissimilar metals make electrical contact in the presence of an?
When two dissimilar metals make electrical contact in the presence of an electrolyte, galvanic corrosion can occur. This phenomenon arises due to the difference in electrochemical potentials between the two metals, leading to the more reactive metal (anode) corroding faster than the less reactive one (cathode). The electrolyte facilitates the flow of ions, exacerbating the corrosion process. To mitigate this, methods such as coatings, sacrificial anodes, or using similar metals can be employed.
What group of elements would most likely be used for electrical wires?
The group of elements most likely used for electrical wires is the transition metals, particularly copper and aluminum. Copper is favored for its excellent electrical conductivity, durability, and resistance to corrosion. Aluminum, while less conductive than copper, is lighter and more cost-effective, making it a popular choice for overhead power lines. Both metals are widely utilized in various electrical applications due to their favorable properties.
Is vanadium a good electrical conductor?
Vanadium has slightly less resisitivity than lead, but approximately 11 times that of copper. It is not normally used as an electrical conductor, but is used in redox flow batteries and certain semiconductor applications.
Are all types of metals good conductors?
No, not all metals are good conductors. Some metals, such as copper and aluminum, are excellent conductors of electricity and heat due to their large numbers of free electrons. Other metals, like lead and stainless steel, are poor conductors because their electrons are not as free to move.

What are metals that are less reactive than alkali metals and alkaline-earth metals?
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
Is iron a good electrical conductor?
Yes, but it's less useful for electronics purposes than other less resistive, more ductile metals like copper, aluminum, silver, gold, etc.
What class class of elements have less electrical heat?
Metals generally have higher electrical and thermal conductivity, while nonmetals tend to have lower conductivity and, consequently, less electrical heat generation. Among nonmetals, noble gases and some semiconductors exhibit the least electrical heat due to their poor conductivity. Thus, nonmetals, particularly those that are inert or have limited conductivity, are associated with lower electrical heat.
What are important properties of acids and bases?
Acids: 1) Taste Sour 2) PH less than 7 3) Proton Donnors 4) Lewis Acids 5) React with Metals to give hydrogen 6) Electrolytes Bases: 1) Taste Bitter 2) PH greater than 7 3) Proton Acceptors 4) Electrolytes

Metals that are less reactive than alkali metals and alkaline-earth metals are?
Almost all the rest of the metals.
Metals that are less reactive than alkali metals and alkaline-earth metals are called?
I believe that the answer you are looking for is Transition Metals.
Metals that are less reactive that aklitlsnd alkaline earth-metals are called?
Metals that are less reactive than alkali and alkaline earth metals are called transition metals. They are typically less prone to reacting with other elements and have distinctive properties such as variable oxidation states and the ability to form colored compounds.

What is used as a conductor in electrical circuits?
Metals such as copper and aluminum are commonly used as conductors in electrical circuits due to their high conductivity. Other materials like silver and gold are also good conductors but are less commonly used due to their higher cost.
