Answer: a) : anode
b. : cathode
c. : anode
Explanation:
Electrochemical cell is a device which converts chemical energy into electrical energy. It consist of two electrodes, anode and cathode.
Oxidation i.e. loss of electrons , which results in an increase in oxidation number occurs over anode.
Reduction i.e. gain of electrons, which results in decrease in oxidation number occurs over cathode.
a. : oxidation : anode
b. : reduction : cathode
c. : oxidation : anode
Answer:
Please mention elements so i can answer it
Explanation:
Your best answer for 1 is B.
Answer: false
Explanation:
When two atoms come sufficiently close together the valence electrons of each atom experience the attractive force of the nucleus in the other atom. The nucleus and the electrons in the inner shell remain unaffected when atoms come close together.
The formula here is:
pH = -log[H+]
3.6 = -log[H+]
[H+] = 2.51 x 10⁻⁴ mol / Liter
The first option is correct.
