Answer:
The value of new pressure will be 1.56 atm.
Explanation:
Using combined gas law :
The combined gas equation is,
![\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
where,
= initial pressure of gas = 2.4 atm
= final pressure of gas = ?
= initial volume of gas = ![6 L](https://tex.z-dn.net/?f=6%20L)
= final volume of gas = 15 L
= initial temperature of gas = ![400 K](https://tex.z-dn.net/?f=400%20K)
= final temperature of gas = ![650 K](https://tex.z-dn.net/?f=650%20K)
Now put all the given values in the above equation, we get:
![\frac{2.4 atm \times 6 L}{400 K}=\frac{P_2\times 15 L}{650 K}](https://tex.z-dn.net/?f=%5Cfrac%7B2.4%20atm%20%5Ctimes%206%20L%7D%7B400%20K%7D%3D%5Cfrac%7BP_2%5Ctimes%2015%20L%7D%7B650%20K%7D)
![P_2=\frac{2.4 atm \times 6 L\times 650 K}{400 K\times 15 L}](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7B2.4%20atm%20%5Ctimes%206%20L%5Ctimes%20650%20K%7D%7B400%20K%5Ctimes%2015%20L%7D)
![P_2=1.56 atm](https://tex.z-dn.net/?f=P_2%3D1.56%20atm)
The value of new pressure will be 1.56 atm.

210 82Pb-----> 206 80Hg + 4 2 He
55 24 Cr----->55 25 Mn + 0 -1 e
76 35 Br + 0 -1 e-----> 76 34 Se
Explanation:
Alpha decay occurs with atoms having high atomic number number. As the atomic number increases, the repulsions between the protons make the nucleus unstable. A point is reached where the attractive forces in the nucleus are unable to hold the nucleons together anymore. Part of the nucleus now breaks off as an alpha particle or a helium nucleus.
Beta decay involves the transformation of a neutron to a proton, electron and neutrino. It decreases the neutron-proton ratio.
The capture of an orbital electron converts a proton into a neutron with the emission of a neutrino. The atomic number of the product nucleus decreases. Orbital electron capture increases the neutron-proton ratio.
