indication that displayed that the reaction had been complete. At this moment, there was observable unreacted zinc granules in which remained at the base of the flask. The reaction was then completed and the flask was removed from the hot plate using tongs, the aluminum foil used to cover the top of the flask was removed. Following that a 250 mL beaker was clean, dried and then weighed. After doing that the mass of the empty beaker was recorded. Then a glass rod was placed across the neck of the flask

The Formula Of A Hydrate I. Purpose The purpose of this experiment is to determine the empirical formula also known as the simple formula of a compund known as a hydrate. II. Safety When around copper sulfate do not get it on your skin, breathe it in, eat, or drink it. If any of that happens notify your teacher. If it gets in contact with your skin wash it off quickly and apply a hand creme. Breathing it in can affect your lungs. If exposed to the chemical and is heavily inhaled go outside

Growing up, Sundays were always a family gathering at my house. All my aunts, uncles and cousins would come over for dinner. Recently, as we have gotten older, hookah is something the cousins have adopted as a custom to engage in after dinner. Smoking hookah is an activity that my cousins and I all enjoy to do together as well as use as a bonding experience. Hookah originated in South Asia and the Middle East, where most of my ancestors are from, and plays a prominent role in the culture and society

crucibles and tongs. During this experiment the timing for the cooling part was very tedious so we had to make sure to time it and allow for the crucible to cool. For Part B of this lab we additionally became familiar with the vented fume hood and how it helps with potential harmful gases and their odors. For part B we were working with the Empirical formula of copper sulfide. To start off we brought all our material to the fume hood, which was two crucibles and covers, a clay triangle, tongs, and a ring

of the crucible and the contents. Place the cover on the crucible and lay on the clay triangle. Heat the crucible and contents gently for 2 minutes. After this time is up, tilt the cover to provide and air opening. Tilt the cover using the crucible tongs. Now, heat the crucible and contents strongly

not in use. Wash hands with soap and water before leaving. Materials/Equipment- Spot (reaction) plate Graduated Cylinder (50 ML) Beaker (150 ML) Beaker (500 ML) Hot Plate Bunsen burner Ring stand w/ metal ring Crucibles with lid Crucible tongs Test tube tongs Spatula Thermometer Electronic or triple beam balance Test tubes Apron and Goggles Procedure- The procedure for this lab includes many simple steps and a few different things we are testing. Our first Procedure was to combine water and

everything else will sift through. Place the rocks into another beaker 3. Pour hot water into the beaker containing sand, salt and Styrofoam then mix. The Styrofoam will float, the sand will sink, and the salt will dissolve. Pick the Styrofoam out with tongs and wait for the sand to fully sink. 4. Prepare a beaker with a funnel and filter paper. 5. Pour the sand and salty water into the filter paper. The water will filter through leaving just the sand, scrape the sand off the filter paper and into a beaker

Introduction The purpose of this lab was to determine which regions of the body have the most touch receptors and in turn which regions of the body have the greatest representation on the somatosensory cortex map. The somatosensory cortex map is located in the parietal lobe and processes tactile information (D. Purves, Augustine, & Fitzpatrick, 2001). According to Neuroscience 2nd edition, the increased representation of specific body areas in somatosensory cortex map is a function of evolution
