The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are

Experiment B10- Photocromism and Piezochromism Reece Harms 4320288 Introduction This experiment investigates an oxidative coupling reaction in an to synthesise triphenylimidazole dimer from 2‚4‚5-triphenyl-1H-imidazole. The resulting compound was investigated for both photochromic and piezochromic properties by way of formation of a stable radical‚ utilizing visual observations and UV-Vis as a means of distinction. Both the oxidative coupling reaction and the dimers interaction with light

Trial # Guess Observation Explanation Trial 1 The dyed red water will not seep into the blue cold water. My guess was indeed correct and red water did not interfere with the blue water. Because the molecules in the blue water are much closer together because its cold and well the red water has warm/hot water and the molecules are everywhere. The molecules in the blue water are so dense that they’re making a layer so that the molecules from the red jar do not come through. Trial 2 I think

Discussion: Conclusions: • For both meters it was noted from plots that the difference in pressures are directly related to the rate of discharge. • Coefficient of discharge have a varying value depending on the rate of discharge‚ where in the Venturi meter the value of Cd increase gradually at first with increasing the rate of discharge till a point approaching one‚ then started to descend with further increment in the rate of discharge. • The Coefficient of discharge " Cd
