Flame lab test Chemistry Introduction The lab test performed was to determine characteristic colors that were produced by specific metallic ions that are shown in a flame. This happens when an electron gains energy; the electron moves from an energy level that’s farthest away and to an empty orbital close to the nucleus with higher levels‚ so one of the electrons gives off energy. A flame test is a visual test where the energy is in the form of a color change and the change can

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher

Chromatography Lab Questions Pre-Lab Questions 1. A pencil is used rather than a pen to mark the “starting line” in step two because a pen or marker while be used to place a small dot of ink in the center of the X that is made with a pencil. 2. Capillary action is filling of pores in a solid with a liquid. Capillary action is caused by spotting or absorption and is allowed to seep or flow through. 3. The type of pen that will probably give better separation in this paper chromatography

Samuel Heidenreich Miss.Tatu Biology March 5‚ 2015 Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as
