Answer:- The daughter nuclide is Gallium with atomic number 31 and mass number 68.
Explanations:- Positron emission is also known as beta plus decay. In this type of radioactive decay in which a proton changes into neutron and a positron and electron neutrino are released.
As the proton changes into neutron, mass number remains same but the atomic number decreases by one unit.
The given element is Ge with atomic number 32 and mass number 68. Mass number decreases by one unit means the atomic number of the daughter nuclide would be 31 and it is Gallium.
The equation could be written as:

Answer:
804 J
Explanation:
Step 1: Given data
- Mass of silver (m): 1.50 kg
- Initial temperature: -7.8 °C
- Final temperature: 15.0 °C
- Specific heat capacity of silver (c): 0.0235J·g⁻¹K⁻¹
Step 2: Calculate the energy required (Q)
We will use the following expression.
Q = c × m × ΔT
Q = 0.0235J·g⁻¹K⁻¹ × (1.50 × 10³g) × [15.0°C-(-7.8°C)]
Q = 804 J
