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:-

Answer:
The pH of the solution is 5.31.
Explanation:
Let " is the dissociation of weak acid - HCN.
The dissociation reaction of HCN is as follows.
Initial C 0 0
Equilibrium c(1- ) c
c
Dissociation constant =
In this case weak acids is very small so, (1-
) is taken as 1.
From the given the concentration = 0.050 M
Substitute the given value.
Therefore, The pH of the solution is 5.31.
