the dye extracted from samples of magnetic bentonite clay and of charcoal through filtration. From the data collected in this experiment, it was found that charcoal was a more effective alternative to use as an absorbing agent in rivers to clear the water of harmful PAHs. INTRODUCTION…

The cinnamaldehyde and water distillate was obtained from the previous lab session and was observed for changes. The oil was on the bottom of the flask. The distillate turned clear when initially it was white. The distillate still had a cinnamon smell. The cinnamaldehyde was now to be extracted from water using an organic solvent. To choose the right solvent for the experiment, the organic solvent must meet certain criteria. It must be miscible with the substance extracted (in this case,…

How does table sugar react with potassium nitrate? Will the ratio between table sugar and potassium nitrate affect the product produced? According to “Smoke Bomb” (2017), smoke bomb is a firework designed to produce smoke when ignited. Smoke bombs are used in various ways such as signalling aircrafts, paintball guns, airsoft guns, military units, self-defence, entertainment and pranks. Smoke bombs was first invented by a British inventor, Robert Yale in 1848. He started by developing…

Parents struggle to find a place that everyone in the family would enjoy. Quality time with the family is very important but difficult to execute. The place that everyone would appreciate is the beach. Specifically, Santa Cruz Beach because of all of the accommodations offered. Every fun memory that I have developed there is unforgettable. For example, the laughs formed over playing football with my family at the beach last summer is one of my favorite. Whether it’s the ocean or the bonfires,…

Following WHMIS, it is vital that safety be a priority when conducting labs. Especially when handling chemicals, the ideal setup of labs should avoid any obstructions and potential hazards that may occur. This is due to the possible dangers: flammable and combustible chemicals (alcohol, sodium), oxidation (hair dye), bio hazardous products (which causes AIDS, rabies), toxic items (lead, benzene), poison (carbon monoxide), corrosive compounds (bleach), dangerously reactive chemicals (fluorine)…

Shot#2 (CU. Straight on; low level): Then the black and grey sneaker is shown on its side view tapping in time with same non-diegetic music as shot #1. A blue and white wrapper falls right next to shoe on the stone pavement as soon as the shoe taps again to the non-diegetic music. (3 secs) Cut to Shot #3 (ECU; straight on): An extreme close- up of a hand is shown opening the top of a red- and white-colored milk carton. In black letters it reads “Thank you for buying Adhor Farms products”. (7…

1. Why is it necessary to have positive and negative controls in this experiment? It is necessary to have positive and negative controls in this experiment to see how variables are affected; therefore, without controls there would be no way to now what would normally happen with the chemical reactants. 2. Describe the movement of each substance in the dialysis bag and the beaker. The movement of glucose in the dialysis bag was that is crossed the dialysis membrane; therefore, it was found…

Introduction: Hot packs work by dissolving a salt, such as calcium chloride, in water to create an exothermic reaction. When salts are dissolved in water it requires energy to break their bonds apart, but energy is also released when the ions are surrounded by the water molecules. If more energy is released than is required to break the bonds, the reaction will be exothermic and will produce heat. In hot packs the water is kept separate from the salt, and when it needs to be activated, they are…

We see trash every day without paying attention. At times we don’t even realize how much trash is thrown away daily. It can be as small as a toothpick, to as big as a vehicle. If you live in a country like the United States of America where plastic, batteries, and other things are thrown away daily, chances are that an average family of four people, can produce as much as twenty pounds of waste per month. People just throw away trash without knowing where that stuff will end up. Solid waste…
