Explanation:
sodium atom is neutral while sodium ion is a charged specie with a charge of +1
Nuclear decay or radioactive decay is a process by which the nucleus of an unstable atom loses energy that is in terms of its mass. The radioactivity may cause an atom to lose whichever of its subatomic particles.
The explanation as why some of the atoms go through nuclear decay while others do not its because of the stability of some atoms. Atoms usually tend to follow octet rule, those which do not follow through this may experience the nuclear decay.
Answer:
The molecular formula of X is C8H9NO2
Explanation:
Step 1: Data given
exact mass of 151.0640
Molar mass of C = 12 g/mol
Molar mass of H = 1.00783 g/mol
Molar mass of O = 15.9949 g/mol
Molar mass of N = 14.0031 g/mol
Step 2: Calculate molar mass of C7H5NO3
7*12 + 5*1.00783 + 14.0031 + 3*15.9949 = 151.02695 g/mol
Step 3: Calculate molar mass of C8H9NO2
8*12 + 9*1.00783 + 14.0031 + 2*15.9949 = 151.06337 g/mol
Step 4: Calculate molar mass of C10H17N
10*12 + 17*1.00783 + 14.0031 = 151.13621 g/mol
The molecular formula of X is C8H9NO2
