The decay mode of cesium-137 is beta decay. This means that the cesium-137 decays into a beta particle and a nuclide with the same mass number, but with a charge number that is 1 more than that of cesium.
Therefore, this means Cs-137 decays into an electron and Barium-137, meaning the answer is choice 1.
Answer:
D
Explanation:
the Same number of proton
Answer:
: 0.5 atm and 
: 1 atm
Explanation:
In order to calculate the partial pressure for each gas , all you need to do is multiply the mole fraction of each gas with the total pressure.
It is given that 
= 1.5 atm
The mole fraction of each gas can be calculated in the following way:
= moles of ÷ total moles present = 
= moles of ÷ total moles present = 
Partial pressure of : 1.5 × = 0.5 atm
Partial pressure of : 1.5 × = 1 atm
Hope that answers the question, have a great day!
