Which of the following statements about nuclear reactions is true?

they do not follow einstein's equation since no changes in mass or energy occur.

they follow the law of conservation of energy only.

they follow the law of conservation of mass only.

they follow einstein's equation, which allows for the conversion of mass to energy.

They follow Einstein's equation, which allows for the conversion of mass to energy is true about nuclear reaction.

Explanation:

The nuclear reactions happen according the Einstein’s equation, i.e.,  when the mass deficit between the weight of the nucleus as a whole and the individual constituent components occurs, this deficit is converted to energy that is released and used for nuclear reactions.

No mass can never be made or destroyed. So is energy. Energy too has to remain constant; there can be a change in the form, energy can be converted into mass or vice versa but the constancy has to be maintained.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

the answer to this question is 3.
