Water filter

while in the apparatus. The crystals were then dried and the yield and melting point were taken. Results • Maleic anhydride = 0.4g (0.004 moles) • Ethyl acetate = 1ml • Hexane = 2ml + some to rinse crystals • Cyclopentadiene = 0.4ml (0.0048 moles) • Filter paper before = 0.18g…

With the large populations being in one tight area out there and since our leaves are basically the world’s air filter, and they are constantly cutting them down for more expansion, they are a large contributor to the world’s pollution whether it be water, air, or even soil. Many other large contributors are, commercial fishing, container ships, and also just drop in population. Commercial fishing as we all know is a large factor in…

As a first step, four water baths will be prepared based on different temperature ranges, in a 600 ml beaker. After that, the probes will be connected to the channels. A rubber stopper assembly will be inserted into 125 ml Erlenmeyer flask, and the plastic tubing will be attached…

Salvinia molesta is an invasive species that has consumed many bodies of water in the states of Louisiana, Texas, Alabama, and Colorado (McFarland et al. 2004). The invasive species originated from South America and the first place it was transferred to was Australia (Room 1983). Eichhornia crassipes also originated from South America (Gopal and Kanta 1981). Lemna sp. is native to many places around the world (Azeez and Sabbar 2012). The extracts were created from E. crassipes roots and shoots,…

CAUTION: It is best not to get dichloromethane on your skin. Gloves are to be worn during this experiment, if improper safety precautions are taken there is a possibility of irritation, and or burning of the skin. CAUTION: Gas will build up in the separatory funnel while you are shaking it, so you must vent the funnel occasionally to prevent the stopper from popping out, causing a mess and possibly getting dichloromethane on your skin. ~During the pre-phase of this experiment it is…

solution in distilled water • Filtering the dissolved solution • Evaporating the water to increase the concentration Equipment 1 beaker 50ml of distilled water Stirrer 1 Funnel Filter paper 1 crucible 1 Bunsen burner 1 heatproof mat 1 tripod 1 teaspoon of soil sample 1 conical flask 1 Pipeclay triangle Method 1. Place the soil sample in the beaker and add 50ml of distilled water and stir until dissolved. 2. Place the funnel into the conical flask and fold the filter paper to fit…

To separate sand and NaCl it must be diluted with water then filtrated using filter paper. The residual water is full of dissolved NaCl since NaCl is water soluble. The NaCl can dissolve in water because of water’s emergent property; versatility as a solvent. Because water is polar, it can break apart other molecules until the molecules are bonded with water. To separate the soluble NaCl from the water a physical change must occur and the water must be heated and evaporated into vapor. Mass was…

heated in a 50℃ water bath. The reaction mixture was heated and stirred for 5 minutes until the salicylic acid dissolved. The mixture was set aside to cool down to room temperature and crystallize in the beaker. Afterwards 6 mL of cold deionized water was added to the crystals (aspirin). The crystals were separated from the mixture through vacuum filtration using a Hirsch funnel. The mixture was washed with 0.5 mL of cold deionized water and the aspirin product was transferred to filter paper.…

's a nice feeling to have betta fish for pet, and steps on how to care for betta fish is very much interesting topic to discuss. They truly can relieve work stress and even anxieties. Of course, who can resist from its flashy color, flaunting tails and alluring appeal? Betta fish is a tropical fish originally came from Asia. They come in different varieties and breed.

I am against the use of chloramines in Stockton’s water. Did you know that it can cause rashes after showering in a small percentage of people? (http://www.foodreference.com/html/a413-chlorinewater.html, Article 3, Paragraph 4) What if that small percentage is you, everyone else is just fine and you are suffering from this rash. It’s also possible for lead from pipes to dissolve into the water, which can cause even more problems. (http://www.foodreference.com/html/a413-chlorinewater.html,…
