The analyses of the mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques, we examined our solutions such as SiO2 (sand), NH4Cl (ammonium coloride), and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions, we made…
