Rf value (retention factor)

Answer 15

distance a compound moves during chromatography

Question 16

formula for Rf (retention factor)

Answer 16

distance substance travels from origin / distance solvent travels from origin

Question 17

hill reaction

Answer 17

process that happens during photosynthesis where electrons from water are being oxidized and the electrons from carbon dioxide are being reduced

calculate Rf

Answer 20

distance pigment traveled / distance to the solvent front
