Respuesta :
The amount of copper deposited is 0.7896 grams.
Given,
t=20min=20*60=1200s
I=2A
Q=It=2*1200=2400C
Here copper releases 2 electrons in the reaction
So, electricity deposited in 1 mole of copper is (number of electron * faradays number)=96500*2=193000 C
193000 C of electricity deposits 63.5 g of Cu.
2400 C of electricity deposits = [tex]\frac{63.5}{193000} *2400=[/tex] 0.7896g of copper.
Copper
The chemical element copper has the atomic number 29 and the symbol Cu. It is an extremely high thermal and electrical conductivity metal that is soft, malleable, and ductile. Pure copper has a pinkish-orange tint when it is first exposed to the air. As a heat- and electricity-conducting material, copper is also utilized for construction. It is also a component of several metal alloys, including cupronickel, which is used to create coins and naval hardware, and constantan, which is used in strain gauges and thermocouples for temperature measurement.
One of the few metals that can naturally arise in a form that can be used is copper.
