which statement correctly compares chemical reactions with nuclear reactions? in chemical reactions, new isotopes are formed. in nuclear reactions, new compounds are formed. chemical reactions can be represented by balanced equations. nuclear reactions cannot be represented by balanced equations. in chemical reactions, small amounts of energy can be absorbed or released. in nuclear reactions, changes in energy are much larger. in chemical reactions, only protons and neutrons are affected. in nuclear reactions, only electrons are affected.

which statement correctly compares chemical reactions with nuclear reactions? in chemical reactions, new isotopes are formed. in nuclear reactions, new compounds are formed. chemical reactions can be represented by balanced equations. nuclear reactions cannot be represented by balanced equations. in chemical reactions, small amounts of energy can be absorbed or released. in nuclear reactions, changes in energy are much larger. in chemical reactions, only protons and neutrons are affected. in nuclear reactions, only electrons are affected.

Answer

Brief Explanations:

  1. Chemical reactions involve only electrons and result in formation of new compounds, represented by balanced equations. Small - energy changes occur.
  2. Nuclear reactions involve protons and neutrons, form new isotopes, and have much larger energy changes. They can also be represented by balanced equations (nuclear equations).
  3. Analyzing each option:
    • Option 1: Chemical reactions don't form new isotopes, nuclear reactions do.
    • Option 2: Both chemical and nuclear reactions can be represented by balanced equations (chemical and nuclear respectively).
    • Option 3: Chemical reactions have small energy changes, nuclear reactions have large energy changes. This is correct.
    • Option 4: In chemical reactions, only electrons are affected, in nuclear reactions, protons and neutrons are affected.

Answer:

In chemical reactions, small amounts of energy can be absorbed or released. In nuclear reactions, changes in energy are much larger.
