How many grams of copper would be deposited during electrolysis of copper salt by a current of 7.50A for 600 hours?
Assume it is a copper 2 salt and no side reactions it would require 96485 x 2 coulombs of charge per mole of copper or per 63.5 g of copper. 1 coulomb is 1 amp.second so 7.5 x 600 x 3600 x 63.5 / (96485 x 2) g = 5331 g Cu
What is the mass of silver metal produced from 6.35 g of copper?
The mass of silver produced is equal to the mass of copper used, based on the Law of Conservation of Mass. So, 6.35 g of copper will produce 6.35 g of silver.
Is copper an ohmic conductor?
Yes of course all transition metals are ohmic conductors. (voltage proportional to current at constant temperature with resistance rising or gradient of V-I graph decreasing at higher temperatures) Believe me I've just done physics A.S.
How can boyle's law be applied in everyday life?
we use his law in everyday life use to inflate a balloon,poping abubble, pumping up a bicycle tire, breathing, filling cheeks up with air, and leting the gas that is air out of are fully filled mouth.
Why is colorimetric estimation of copper done at 620 nm?
Copper can form a colored complex with a reagent (such as neocuproine) that absorbs light at 620 nm. By measuring the absorbance of this complex at 620 nm, the concentration of copper in a solution can be calculated based on Beer-Lambert's law.
Who did Michael Faraday associate with?
He is a physician and formulated faradays law of electrolysis
Formula for finding current rating of mccb?
faradays second law
Who formulated the law of electrolysis?
FARADAY
What is the first law of Faraday's first law of electrolysis?
First LawThe quantity of a substance produced by electrolysis is proprotional to the quantity of electricity used.
Does copper need a voltage to produce a current?
Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.
What does cops stand for in law enforcement?
The word "cop" (plural form "cops") is the shortend form of the slang word "copper." It refers to the copper metal badges law enforcement officers used to be issued, and in turn has been applied to those who wore them.
What is maxwell's counter part to faradays law?
A magnetic field is induced in an region of space in which and electric field is changing with time.
Does faradays law of electromagnetic induction explains wireless transmission of electricity?
not entirely, you need Maxwell's equations for a complete explanation
Why a negative sign appears in the equation of faradays law of electromagnetic induction?
the inducedd e.m.f and the change in magnetic flux have opposite direction
How many grams of copper would be deposited during electrolysis of copper salt by a current of 7.50A for 600 hours?

Define Faraday second law of electrolysis?
Faraday's second law of electrolysis states that the amount of a substance deposited or liberated at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte. It quantitatively relates the amount of a substance produced in electrolysis to the charge transferred during the process.
Who discovered the principles?
Basically all the motors run by "Electromagnetic induction" principle which was set by Michael Faraday.This principle also known as "Faradays law of electromagnetic induction".
