ale4655 [162]
The moles  of disodium edta  used is  calculated  using  the  below  formula


moles =molarity  x  volume in  liters

molarity=0.050m
volume  in  liters = 22/1000=0.022 L

moles  is  therefore=  0.022 x0.050  =1.1  x10^-3  moles  of  disodium  edta

Write a nuclear reaction for the neutron-induced fission of u?235 to produce te?137 and zr?97. how many neutrons are produced in
alexandr1967 [171]
This is a neutron induced fission, therefore a neutron will be added to the U²³⁵ to cause the reaction, and thus it will be added to the left side. There will be unknown number of neutrons produced and thus we put this on the right hand side.
n₁ + U²³⁵ = Te¹³⁷ + Zr ⁹⁷ + xn1 ( n1 to mean a neutron of mass 1)
To balance the masses on both sides of the equation;
1 + 235 = 137 +97+ x
x = 2 
the end reaction will be
n₁ +U²³⁵ = Te¹³⁷ + Zr⁹⁷ + 2 n₁
