Bunsen burner

crucible, a Bunsen Burner, a 150 mL Erlenmeyer flask, a thermometer, a pressure gauge, a syringe, two 50 mL beakers, magnesium (Mg), Copper(II) Carbonate Hydroxide Hydrate (Cu2CO3(OH)2 x H2O,) 6M Hydrochloric acid (HCl), Zinc (Zn),…

rosea, leading to them being killed off, or the petri plate could have been left open too long to foreign materials, leading to bacterial growth that was not intended. Also, the inoculating loop could have not been sterilized correctly with the Bunsen burner. Making sure the loop is not too hot when doing the inoculation, leaving the petri plate as closed as possible when working with it, and also making sure the loop is kept in the flame for a longer amount of time, are all things that could be…

this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs. Procedures:…

through the system, transferring the unwanted heat in the liquid in the radiator to the cold air, making it hot air and spitting that out of the system. The most common example in the real world is a pot with water in it, resting on a burner. The heat made from the burner is quickly transferred to the pot and then heating up the water. The thing that separates this from conduction is that the molecules directly touching the pot receive the energy transferred, and move away quickly, only to be…

Turn the Bunsen Burner on medium and place 2 beakers of water on the surface. 7. Place 1 thermometer in each of the beakers of water 8. Take test tube number 1 and put it in beaker number 1, on the burner. 9. Take test tube number 2 and put it in beaker number 2, on the burner. 10. Monitor the temperature of test tube number 2. (The water must stay at 70oC take on and off burner as needed) 11. Test tube number 2 needs to be at a boiling temperature…

Introduction Life could not exist without microorganisms: plants depend on microbes to obtain soil and cows need microorganisms to digest cellulose. Microbes degrade waste and they live in our bodies to keep us healthy. Microorganisms are also used to make vaccines and antibiotics. However, some bacteria are known for causing diseases such as the common cold, AIDS, Herpes, and Chicken Pox. Knowing the identity of microbes is essential for knowing the causative agent of a disease in order to…

Title Determining the Empirical Formula of Magnesium Oxide Introduction Chemical formulas imply the arrangement of compounds. Empirical formulas are the simplest whole number ratio of the elements present in a compound (Owen, 2014). However, the actual amount of each type of atom that a compound is consisted of is called the molecular formula. For that reason, the deduction of the empirical formula and the molar mass of a compound is required to determine the molecular formula of the compound.…

surface of the nutrient agar. The plate was then incubated at (Ryerson Department of Biology, 2017). Materials used in experiment 1.2A: Inoculating loop, Nutrient broth tube Materials used in experiment 1.2B: Inoculating loop, Nutrient broth tube, Bunsen burner, Flint In experiment 1.2B the end of an inoculating loop was brushed against one’s finger. A nutrient broth tube was then…

The organic care hand wash had 2cm worth of inhibition zone, dettol hand wash had 1cm, palmolive had 0.9cm and dettol santisier had 0.8cm. In terms of which one was the most ocst efficient, dettol hand wash cost $2.00, while organic care costs $4.00. The hypothesis was refuted, as it was said the popularity of the product would dictate its effectiveness and efficiency, yet the most popular product is dettol. Dettol is seen in everywhere, on hygiene posters, tv ads, in public bathrooms etc., and…

The predicted results / graph shows that dettol hand wash will be the most effective and have a marginally better zone of inhibition than dettol hand sanitiser, while the control hat contains nothing, will be the least effective. Experimental Procedures Independent Variable An independent variable is a variable that remains unchanged and stands alone. My independant variable is each hand cleaning product used. Organic Care orange and ginger antibacterial hand wash, Palmolive antibacterial…
