For this to occur‚ a heterogeneous mixture has to be placed into a distiller‚ in this experiment a solution of 1:1 water and methanol was distilled. When distilling substances there are various methods of distillation that can be used. In this lab‚ simple and fractional distillation was used. The simple distiller is composed of a 100ml round bottom flask that is attached to: a 3-way adapter‚ thermometer‚ condenser and vacuum adapter. The apparatus is heated up by placing a powermeter at the

Laboratory safety is an integral part of any lab experience. If the participants are unkempt or precarious‚ they can easily cause a huge accident or even tragedy. When working in the lab‚ so many different hazards are faced. The rules of the laboratory are in place to ensure that one does not hurt themselves‚ let alone everyone else in the room or even the whole building. Each person needs to be responsible for themselves‚ while also watching for potential dangers others may not notice. The first

Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry
