Keeping it Liquid Introduction: Phase changes within our world play a key role in how substances can be manipulated‚ and formed. A phase change is‚ “a change from one state (solid or liquid or gas) to another without a change in chemical composition” (Collins Italian Dictionary‚ 2016). Moreover‚ in this experiment‚ the use of tert-butanol was needed to perform phase changes. Tert-butanol is colorless oily with sharp odors‚ mixes with water‚ and has a freezing point of 78 degrees Farenheit (PubChem

solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a high melting point‚ soluble in water and insoluble in 2-propanol; some of the physical properties of camphor are a strong odour‚ soft‚ a low melting point‚ insoluble in water and soluble in

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

You can do this while you are at home‚ at work or before doing your workout. VapoRub incorporates levomenthol‚ a strong white glass with mint flavor. If ever that this part is utilized alone‚ it might cause rash‚ however when paired up with Vicks‚ it is totally safe because of the fact that it incorporates eucalyptus oil. Camphor is another

18th and 19th century‚ it became well known that chemicals such as camphor can induce seizures to help with mental illness.1 In 1934‚ a Hungarian psychiatrist‚ Ladislaw Meduna‚ empirically pursued his theory on the relationship between seizures and schizophrenia using camphor oil. He wanted to see if he could cure a patient with catatonic schizophrenia by inducing epilepsy in the patient through injecting the patient with the camphor oil. After several of these treatment sessions‚ the patient was reportedly

HOW TO GET RID OF SILVERFISH NATURALLY Silverfish are slivery bristletail insects that live in buildings and feed on starchy materials. These fairly harmless‚ serpentine creatures aren’t pleasant to have around the house. They feed on books‚ dead skin cells‚ and thrive in dark‚ wet spaces. Once you discover an infestation‚ you can get rid of the silverfish bugs by with insecticides or various methods you will learn about from this article. Silverfish bugs are not harmful to humans. However‚ they
