Chemistry Lab Report Purpose The purpose of this lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette

Identify the barriers to communication and elaborate on them. Communication refers to an act‚ or means of conveying information from one individual to another. The word communication is derived from Latin word”communis” which means “to share”. Hence communication is a process in which facts ‚ ideas‚ thoughts‚ opinion and emotions are exchanged by two or more people.

Similarities and reflection of our values make us belong to a group‚ but the differences are barriers that stop ourselves from being recognized as an indivisible part of it. Belonging and identity are inseparable;

Personal Care period 4 Michelle Manobanda 2012 The FDA permits the use of mercury compounds in eye makeup at concentrations up to 65 parts per million. The preservative thimerosol‚ found in some mascaras‚ is a mercury-containing product. Mercury is associated with a host of health concerns including allergic reactions‚ skin irritation‚ toxicity‚ neurological damage‚ bioacculumation‚ and environmental damage. Mercury readily passes into the body through the skin‚ so normal use of the product

Objective: To successfully separate and identify all three unknown cations‚ found in a mixture and belonging to one of two specific groups (2 from one and 1 from the other). In order to do this we will be using various tests and reactions and observing the effect they had on our solution.

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)
