Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held in the flame

Chemical T ests for Unknowns Chemical tests have been developed as a means of identifying what functional groups are present in an unknown compound. Since IR and NMR spectroscopy has been developed‚ they are no longer critical to unknown analysis‚ but they can still be useful for confirming what you have determined by spectroscopy. Some of them look cool too! In order for a chemical reaction to work as a chemical test‚ it must 1) create a visible result (a color change‚ a precipitate‚ etc)

Jesus is challenging the Pharisees to look past their trust in laws and rules to try and see that everyone has worth. Jesus can see the worth of everyone‚ but the Pharisees can only see worth in people who are considered pure. Jesus uses a verse from Hosea 6:6 saying “go and learn what this means” he is trying to tell them that rituals should not replace the act of love or mercy.12 Ethical Analysis The ethical focus of the story of the Tax Collector of Jesus seeing the infinite worth
