Why do stars shine?. Nuclear reactions. Fusion and fission reactions. How nuclear reactions can create energy. Why is it hard to get fusion nuclear reactions to occur?. These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base..
