Answer:
11
Explanation:
The atomic number = number of protons. The mass number (23) = sum of number of neutrons and protons. Since you know the mass number is 23 and it has 12 neutrons, 23-12 gives you 11 protons, so its atomic number is 11.

The specific heat capacity of the metal is calculated as follows
heat energy = Mc delta T
heat energy (Q) = (711 j )
m=mass (41.1 g)
c= specific heat capacity =?
delta t = change in temperature( 94 -22=72)
c= Q/m delta T
c=711 j / (41.1 g x72) = 0.240 j/g /k
Noice but I don’t get why was this necessary
