This is right
Reduce the concentration of NICO4
It only takes mercury 88 days to go around the sun, and if the man is 50 years old he would be 18,250 days old, so he would've gone around the sun 207.39 times.
Oxidation half reaction is written as follows when using using reduction potential chart
example when using copper it is written as follows
CU2+ +2e- --> c(s) +0.34v
oxidasation is the loos of electron hence copper oxidation potential is as follows
cu (s) --> CU2+ +2e -0.34v
Explanation:
Atomic number means the number of protons an atom holds. Whereas mass number equals (number of protons + number of neutrons).
The given figure shows that there are 9 neutrons and 8 protons.
Therefore,
mass number of the atom = number of protons + number of neutrons
= 8 + 9
= 17
Hence, mass number of the atom is 17 and atomic number of the atom is 8.
