Answer: 4.56 Joules
Explanation:-
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed = ?
m= mass of substance = 2.5 g
c = specific heat capacity =
Initial temperature = = 25.0°C
Final temperature = = 29.9°C
Change in temperature ,
Putting in the values, we get:
The heat absorbed by gallium must be 4.56 Joules
<u>Answer:</u> The daughter nuclide formed by the beta decay of given isotope is
<u>Explanation:</u>
Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.
The released beta particle is also known as electron.
We are given:
Parent isotope =
The chemical equation for the beta decay process of follows:
Hence, the daughter nuclide formed by the beta decay of given isotope is
