Answer:
The tendency of metals to lose electrons inorder to get stability is called electropositive nature ofmetals. In general most of the metalslose electrons from their valence shell due to weak force of attraction on the outermost shell.
Answer:
This really depends on what you belive in honestly, as a christian i belive a supreme being created all but school says something happend with bacteria and evolution or something lol. If this was a serious question and you need an answer for school just search up the evolution theory
Explanation:
Answer:- 
for the reaction is -58 kJ/mol.
Solution:- Oxidation half reaction taking place at the anode is--
= 0.14 V
Reduction half equation taking place at the cathode is---
= -0.04V
for the cell = 
for the cell = -0.04V + 0.14V = 0.10V
Now we could easily calculate by using the below formula--
= -nF
where n is the number of electrons transferred in the over all reaction. Looking at two half equations the value of n is 6.
F is Farady constant and it's value is 96500 C/mol.
Plugging in the values in the formula...
= -(6)(96500)(0.10)
= -57900 J
Since, 1000 J = 1 kJ
So, = -58 kJ/mol
