Question

Which statement illustrates the difference between a chemical reaction and a nuclear reaction? A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass. A nuclear reaction releases less energy per gram and appears to violate the law of conservation of mass. A nuclear reaction releases more energy per gram but does not appear to violate the law of conservation of mass. A nuclear reaction releases less energy per gram but does not appear to violate the law of conservation of mass.

Answer 1

its A as a nuclear reaction tends to release a lot of energy and it seems to violate the laws of conservation of mass as some of the atoms mass is converted into energy

hope that helps

Answer 2

A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.

Step-by-step explanation:

In a chemical reaction, the reactant molecules undergo chemical reaction and forms product molecules. The total mass of reactant molecules is equal to the total mass of product molecules, thus chemical reaction obey law of conservation of mass.

In nuclear reaction also , there are some reactants which get converted to products. There is evolution of large amount of energy.

Now, in nuclear reaction the total mass of reactants is not exactly the same as of products as some of the mass gets converted to energy.

thus nuclear reactions may violate the law of conservation of mass.
