Answer:
0.0702J/g°C the specific heat capacity of the metal.
Explanation:m
where,
Q = heat absorbed by metal = 186.75 J
= Mass of metal= 19 g
= Initial temperature of metal =
=Final temperature of metal =
= specific heat of metal= ?
0.0702J/g°C the specific heat capacity of the metal.

Correct Answer is : 54 131Xe
Reason:
Emission of beta particle from radioactive material increases atomic number by one, but atomic mass number donot change.
In present case, the reactant is 53 131 I. When, iodine emits beta particle i.e. electron, it atomic number increases by one. Hence, it gets converted into Xe. Atomic number of Xenon is 54.
