Questions & Step-by-Step Solutions

In nuclear reactions, what is conserved? (2022)
  • Step 1: Understand what a nuclear reaction is. It involves changes in the nucleus of an atom.
  • Step 2: Learn about conservation laws. These are rules that tell us certain quantities remain constant in a reaction.
  • Step 3: Identify the two main quantities that are conserved in nuclear reactions: mass and charge.
  • Step 4: Mass conservation means that the total mass before the reaction equals the total mass after the reaction.
  • Step 5: Charge conservation means that the total electric charge before the reaction equals the total electric charge after the reaction.
  • Step 6: Remember that these conservation laws are fundamental principles in physics, meaning they apply to all nuclear reactions.
