An example of a single replacement reactions is the polishing of silverware by soaking with aluminum. Silver reacts with Sulfur, S, to become Ag2S. Aluminum replaces the silver, Ag, in this reaction. Which of these is the correct balanced chemical reaction for this? A. Ag + Al2S -> Ag + Al2S3
B. Al + Ag2S -> Ag + Al2S3
c. 2Al + 3Al2S -> 6Ag + Al2S3
D. 2Ag + 3Al2S -> 6Ag + Al2S3

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
