Question 47 Which element is most active? a. gold b. hydrogen c. platinum
Question 47 Which element is most active? a. gold b. hydrogen c. platinum
Homework Answers
answer : b. hydrogen
explanation:
in the electrochemical series hydrogen electode potentila = 0.00 V
but gold and plantinum electrode potentails are positive which are below to the hydrogen these are inactive.
note : the elements which are above to the hydrogen are more active and the elements whicha re below to the hydrogen are less reactive in the electrochemical series .

The single most important use of the element gold is for wires that join integrated circuits to the conducting pads that then connect microelectronic chips with external circuitry. A typical application uses gold wires 1.0 milmil (0.001 inch) in diameter and 45 milmil long. Although the current under normal conditions is much less, such a wire will fuse (that is, melt and interrupt the current) when the current exceeds some 660 mAmA. A) Find the current density in the wire...
