The three most prevalent types of chemical reaction introduced are precipitation, oxidation-reduction and:
ARadioactive decay
BPhase transitions
CAcid-base reactions
DNuclear fission
Answer & Solution
Correct answer: C. Acid-base reactions
1. Reactions are grouped by what is actually transferred between species.
2. One transfers ions into an insoluble solid, one transfers electrons, and one transfers protons.
3. The three most prevalent types of chemical reactions introduced are precipitation, acid-base, and oxidation-reduction.
4. Nuclear changes are not chemical reactions at all.
