How thick a layer of nisi will be formed

Question

Problem

1. If 20 nm of nickel reacts with overabundance of silicon, how thick a layer of NiSi will be formed? Densities: Si-2.3 g/cm³, Ni-8.9 g/cm³ , NiSi-7.2 g/cm³.

2. CoSi₂ is formed by cobalt thin-film reaction with silicon. What is the position of the CoSi₂ surface relative to the original silicon surface? Densities: Co-8.9 g/cm³, CoSi₂-5.3 g/cm³.

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
