Answer:

Explanation:
Beta decay conserves the lepton number. In
decay, the atomic number of the element increases which is accompanied by the release of an electron antineutrino,
.
For example:-

The
decay of silicon-32 is shown below as:-

D. radioactive isotopes are one of the environmental waste products of nuclear energy.
Answer:
96.99 C degree change
Explanation:
480 cal / ( 150 g * .033 cal/g-C ) = 96.99 C
PH=-log[H⁺]
pH=-log(1.87×10⁻¹³)
pH=12.72
I hope this helps. Let me know if anything is unclear.
