Ok and? What happened? Where is the question
Answer: 1.19 V
Explanation:
Standard potential for an electrochemical cell is given by:
= standard electrode potential =
The 
values have to be reduction potentials.
Given:
Cadmium is losing electrons , undergo oxidation and thus act as anode. mercury is gaining electrons, undergo reduction and thus acts as cathode.
= standard electrode potential =
Thus the standard potential for an electrochemical cell with the cell reaction is 1.19 V.
Answer:
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings
Explanation:
Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase. This is a measure of the readiness of an atom to gain an electron. When an atom gains an electron readily, it has a high electron affinity.
- The electronegativity is a property that combines the ability of its atom to lose and gain electrons.
- It is expressed as a number that describes the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
Therefore , we see that an atom with a high electronegativity will have a very high affinity to gain electrons. It will want to attract electrons by all means to itself.
