how to calculate the n factor for redox reaction involving complex scenarios and more than two exchanges..
Entropy (S) is a molecular 'disorder', or more precisely 'the number of microscopic arrangements of energy possible in a macroscopic sample'. Entropy depends strongly on the state
Calculate the amount of heat required to raise the temperature of an 58 sample of water from 34c to 64c. Express your answer using two significant figures
in the nucleus of any atom,the no. of protons and the no. of neutrons are same.Also in the nucleus the protons and the neutrons are intermixed not remain seperated.In nucleus two protons never touch each other because between any two proton there is always a neutron which contradicts the force of repulsion.
BECAUSE THE REPULSIVE FORCE OF PROTONS IS LESS THAN THE ATRACTIVE FORCE BETWEEN NUCLEONS.
