In an isochoric process, the increase in internal energy is equal to:
the sum of heat absorbed and work done
the work done
heat absorbed
heat evolved
75 c.c. of N/5 H2SO4, 10 c.c. of N/2 HCl and 30 c.c. of N/10 HNO3 are mixed together. The strength of the resulting acid mixture is:
0.1N
0.2N
0.3N
0.4N
Which will have maximum ionization energy?
Na
Mg
K
Bi
B.
Mg
Among all the options given, Magnesium has the highest ionization energy. It is because magnesium has one more proton in its nucleus to hold on to the electrons in the 3s orbital.
