The Controlled Substances Act (Marijuana Prohibition) CLN-4U Unit One Essay Cailey Bazik CLN 4U – Unit One Essay Controlled Substances Act Marijuana Prohibition The Controlled substance act pertaining to Marijuana has been a long on going battle as to whether marijuana should be legal in Canada and taken out of this act. The law behind the drug has a long history and many failed attempts at decriminalization. There are both positive and negative effects to this law‚ but I believe the

will recover them into their salt forms and then purify them by recrystallization and identify them by their melting points. Procedure: Extraction of Carboxylic Acid A pre-weighed (0.315g) mixture of Carboxylic acid‚ a phenol‚ and neutral substance was placed into a reaction tube (tube 1). tert-Butyl methyl ether (2ml) was added to the tube and the solid mixture was dissolved. Next‚ 1 ml of saturated NaHCO3 solution was added to the tube and the contents were mixed separating the contents into

What Substance Will Melt Ice the Fastest Have you ever wondered which substance melt ice the fastest? My question is how does the material on ice effect the rate the ice melts? To test this I will put sand‚ sugar‚ and salt on ice in separate containers. Next I will check every hour after I put the ice in the refrigerator to watch until one container’s ice has been half melted. To keep this experiment valid I will keep the amount of ice‚ the time‚ and the amount of materials the same. In my experiment

We will be adding different substances such as table salt‚ citric acid‚ and sugar. The scientist’s problem statement is “What kind of substances make gel the strongest?” The independent variable will be the different additives (Table salt‚ citric acid‚ and sugar) which will be added using tablespoons. The dependent variable is the strength of the gel which will be measured using a scale of 10. The constant variable is the type of gel used and the amount of substance added to the gel which will be

The Effect of Molecular Weight on the Diffusion Rate in Substances Nadjah B. Hadji Amer Gladys A. Oliveros Rochelle R. Yaῆez Jan Remon B. Caliguid Group 2- Sec. W78-1 August 14‚ 2013 A scientific paper submitted in partial fulfilment of requirements in Biology 101.1 under Prof. Kimverly Hazel Coronel‚ 1st sem‚ 2013-2014 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using the agar-water gel test. The agar-water gel set up was composed of a six petri

Spinoza states‚ “there cannot be more than one substance of the same nature”. I want you to realize that we would repudiate the meaning of substance if there were more than one with a similar trait. Since if there were more than one with a similar quality‚ at that point one would impart a trademark to another‚ which implies that reasoning one includes pondering another‚ which repudiates the meaning of substance as self-caused. We realize that substance must exist‚ since it is characterized as self-caused

has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20.25cm) as compared to HCl which has a greater molecular weight (36.4611g/mole) and diffused with dave=16.38 cm. A white ring of smoke formed closer to the heavier substance. The agar-water gel set-up used a petri-dish of agar-water gel with three wells on it. A drop of potassium permanganate (KMnO4) was put on one well‚ a drop of potassium dichromate (K2Cr2O7) was put on the other and a drop of methylene blue was put

Purpose: The purpose of this lab was to calculate the amount of time that was spent by a cell in each of the phases of mitosis. Also‚ it is used to be able to compare the process of mitosis between plant and animal cells. Background: • Mitosis: This is the process by which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei. • Interphase: This particular stage is divided into three phases‚ G1 (first gap)‚ S (synthesis)‚ and G2 (second

There is a positive correlation between the height at which the tennis ball was dropped and the amount of energy that it held. This energy was measured through the amount of gravitational potential energy that the tennis ball had before it was dropped‚ and by the amount of work it had done when displacing the sand. As shown in Table 2‚ when the tennis ball was dropped at a height of 1 meter‚ it only possessed a potential energy of 0.569 J. When dropped from 5.5 meters‚ it held a potential energy
