The balanced nuclear equation for the reaction is

²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm +  ⁷⁸₃₀Zn + 3(¹₀n)

From the question given above, we were told that:

A fast-moving neutron strikes a ²³⁵U nucleus. The nucleus shatters producing ¹⁵⁵Sm, ⁷⁸Zn, and three neutrons.

The nuclear equation can be written as follow:

Neutron => ¹₀n

Uranium => ²³⁵₉₂U

Samarium => ¹⁵⁵₆₂Sm

Zinc => ⁷⁸₃₀Zn

Uranium + neutron —> Samarium + Zinc + 3 moles of neutron

²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm +  ⁷⁸₃₀Zn + 3(¹₀n)

 

 The nuclear equation above is balanced.
