Explanation :
Nuclear fission : It is a process in which a heavy nuclei absorbs a neutron, they split or fission into two small nuclei and 3 neutrons.
Atomic number of Cf = 98
Atomic mass of Cf = 252
Atomic number of Te = 52
Atomic mass of Cf = 136
Atomic number of unknown element = [(252 + 1) - (136 + 3)] = 114
Atomic mass of unknown element = 98 - 52 = 46
So, the unknown element is, palladium (Pd)
The complete nuclear fission of a californium atom will be,
Hence, the missing part is,

Answer:
Explanation:
Hello,
In this case, since the reaction between HCl and NaOH is:
We notice a 1:1 molar ratio between the acid and the base, for that reason, in the equivalent point we find:
Thus, in terms of concentrations, we have:
Hence, we solve for the concentration of the acid to obtain:

Answer:
When a magnesium atom reacts with an oxygen atom, magnesium gives up its two valence electrons and becomes a positively charged ion, i.e. a cation, Mg2+ … The cation and the anion will then be attracted to each other by way of the electrostatic force of attraction → an ionic bond is formed.
