in reaction a, each sodium atom gives one electron to a chlorine atom. in reaction b, an isotope of oxygen decays to form an isotope of nitrogen. which statement best describes the energy that is released per gram by these reactions? reaction a releases more energy than reaction b releases. reaction b releases more energy than reaction a releases. reaction a and reaction b release equal amounts of energy. neither reaction a nor reaction b releases energy.

Answer

Explanation:

Step1: Identify the reaction types

Reaction A is a chemical reaction (sodium - chlorine reaction forming sodium chloride through electron - transfer in ionic bonding). Chemical reactions involve changes in electron arrangements and relatively small energy changes per gram. Reaction B is a nuclear reaction (radioactive decay of oxygen isotope to nitrogen isotope). Nuclear reactions involve changes in the nucleus and release much larger amounts of energy per gram compared to chemical reactions.

Step2: Compare energy releases

Based on the nature of chemical and nuclear reactions, nuclear reactions release far more energy per gram than chemical reactions. So reaction B (nuclear decay) releases more energy per gram than reaction A (chemical reaction).

Answer:

Reaction B releases more energy than reaction A releases.
