Municipal solid waste

This paper will give you a background on freezing point and salt. Like what is freezing point and what does this affects. Also what would happen if you put salt in ice water if there is a effect to the ice and water. This paper will give background about basic chemistry of salt. Also it will give you some background on ice cream. How ice could effect ice cream. Water has the freezing point of 0 degrees Celsius. If you put a ice cube in water the rate of freezing and melting aren't changing. If…

amount of medical waste disposed. My goal for studying this sight is to see what possible policies could be implement to decrease waste production while also follow the strict guidelines for patient safety. Approximately 6,670 tons per day of “hospital waste” generated in US hospitals, which is about 1% of all municipal solid waste made yearly (Mochungong 2011). “Hospital waste” refers to all waste (biological or non-biological) that is discarded that comes out a hospital. “Medical waste” is the…

Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

of companies of high velocity and high mass. Hydrophobic lense coating is a thin layer of liquid that can be put onto eyeglasses or eye shields. It gives lenses extra protection and comes with other advantages. It can help prevent liquids and solids from building up on a lense. Hydrophobic lense coatings are compatible with…

Did you know, if you add salt or ice to anything cold the temperature drops? In my experiment, I wanted to find out if different materials impact the rate of ice melting. Before starting this experiment, I know sugar and salt dissolve in water and sand turns into mud. I predict that the results of this experiment will be that the sugar and salt will make the ice melt at a faster rate than the sand because sugar and salt dissolve in water and sand does not. To complete this experiment I will…

The difference between Oceans with salt, and freshwater lakes with no salt, is that salt water takes longer to boil because of the molecular properties. The salt increases the boiling temperature, which makes the tendency for the water to evaporate is greater than the tendency for the water to remain on a molecular level. When the salt is added, the phenomenon known as “boiling point elevation” occurs. Which, involves the old school chemistry the solute, the solvent, and the solution. Chefs…

the ice had melted. Then in step fifteen, vacuum filtration was used to separate the solid from the ice-col mother liquor. The solution was stirred to suspend the solid and the crystals were poured onto the Hirsch funnel. The reaction tube was washed with a small amount of ice water to wash any impurities off the surface of the crystals. In step twenty-one, the solid was transferred to a reaction tube and the solid was recrystallized with a small amount of 95% ethanol. It was observed that it…

bath to melt them. This separated out the components within them- making it easy to measure their percentage value. I found the regular margarine to be made up of 14.5% solids, 64.2% oils, and 21.3% water. Next, I used the same method as before, and found the percentage of each component of the light margarine to consist of .8% solids, 42.9% oils, and 56.3% water. After that, I found the percent error of my calculated amount of each part of both margarine types. I determined my percent deviation…

Dry Ice Properties Dry ice is a translucent white solid that is also odourless, non-toxic, non-flammable and slightly acidic substance (Department of Biology, 2013). Dry ice is the solid phase of carbon dioxide gas with the chemical formula of CO₂. It consists of two oxygen atoms bonding with one carbon atom. Dry ice has a low melting point of -79°C and it is also denser than air therefore when it sublimates to CO₂, it will replace O₂ in the environment and sink to low areas. Dry ice is a…

two different compounds switch places” (Lew 40). This means that one of the reactant’s molecule “trades” places with another from another compound to form products, like a precipitate, hence the term double-replacement. A precipitate is usually a solid insoluble product of a reaction, compared to the other soluble aqueous molecules in the formula. Its creation is what characterizes precipitation reactions since it is what the reaction is named after. The precipitates can look like a powdery or…
