Bombarding plutonium-239 with an alpha particle creates an isotope of curium. balance the equation. 239 94 pu + 4 2 he → a b cm + c d n identify the values for the unknown letters. a is b is c is d is

Value of a is 242, Value of b is 96, Value of c is 1 and Value of d is 0.

Explanation:

It is given that an isotope of plutonium is bombarded with an alpha particle which is also known as a helium particle.

The equation for the bombarding of alpha particle to plutonium-239 follows:

The mass of neutron released is +1 unit and charge is 0.

As we know that every equation must be balanced and must follow law of conservation of mass.

Mass on the reactant side = Mass on the product side

Mass on reactant side = 239 + 4 = 243 units

Mass on the product side = Mass of curium + 1 = 243

So, mass of curium comes out to be 242.

And, atomic number of curium = 94 + 2

Thus, the balanced chemical equation follows:

Hence, value of a is 242, Value of b is 96, Value of c is 1 and Value of d is 0.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
