According to law of conservation of mass, the mass can neither be destroyed nor created in a chemical reaction. The mass of reactants and mass of products are equal in a chemical reaction.
The reaction between A and B (reactants) to form C and D (products) is given as:
The mass of A = (given)
The mass of B = (given)
The mass of reactant = mass of A + mass of B
Substituting the values:
The mass of reactant =
The mass of C =
Let the mass of D =
So, the mass of product = mass of C + mass of D
Substituting the values:
the mass of product =
According to law of conservation of mass:
the mass of reactant = the mass of product
Substituting the values,
Hence, the amount of D produced in the reaction is .
Answer: D) helium.
Explanation:
Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.
Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.
Example:
Thus when deuterium and tritium , the two isotopes of hydrogen are fused, a heavier nuclei helium is being formed from two smaller nuclei releasing a neutron.
