Carbonate

concentration of acid do to shells? Due to earth’s increasing carbon dioxide (CO2) rates scientists have shown that it can make shells , skeletons and corals up to one-third lighter in weight. As the ocean water becomes more acidic it lowers the calcium carbonate available to aquatic animals. ‘Scientists have predicted that the increase in ocean acidification could significantly reduce the ability of these creatures to build their casings, potentially devastating them and causing rippling…

substances found in tea. The two major substances that the caffeine was separated from are cellulose and tannins. Due to the insolubility of cellulose in water, it was easily extracted. Tannins are soluble in water but were neutralized with sodium carbonate to produce water-soluble salts. Caffeine is soluble in methylene chloride which allowed separation of tannins from caffeine because water-soluble salts are insoluble in methylene chloride. The experimental melting point observed in the…

natural resources. But some of its natural resources are very rare and are very expensive. But on the other hand, they don’t have many needed resources such as wood, natural gas, and coal. The resources that Haiti has are bauxite, copper, calcium carbonate, gold, marble, and hydropower. Haitians pan for gold everyday just to find pieces of gold. Whenever they have spare time, they go to rivers and streams full of mud and start panning for gold. Panning for gold could be the extra dollar. So…

How does the salt free water softener work? The salt free water softener can use a couple of different methods. One method includes using a crystal structure made up of calcium carbonate that absorbs minerals from the water. As more minerals build up on the crystal structure, it eventually breaks off, and continues to attract minerals as it flows downstream. Another salt free method is to use a resin plated ceramic surface that creates molecular patterns on it. As water flows past the ceramic…

In this lab, we tested different experiments on a candle flame in order to better understand properties, combustion, and states of matter. We recorded many observations that could help us reach a conclusion using what we saw happen. When we observed the regular candle flame, we concluded that the heat of the flame vaporizes the liquid wax. Then, we blew this candle out and took a different lit candle into the smoke trail from the burnt out candle. The wax vapor in the smoke is combustible,…

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

gives the shines metal a greenish-blue outer layer called a patina. “Patina is a green substance the naturally forms on copper and bronze, sometimes called verdigris, usually consist of varying mixtures of copper chlorides, sulfides, sulfates and carbonates, depending…

Uranus: Uranus was discovered in 1781 by a British Astronomer named William Herschel, using a 6 inch telescope. At first he thought that it might be a nebulous star or even a comet, but after continued observation, he realized that it appeared to be a disk in the sky that moved relative to the stars. The movement was far too slow to be a comet and soon enough he realized that he had discovered the 7th planet at the time. At first, he wanted to name it Georgium Sidus which translates to…

of which 90% or more are iron sulphide such as pyrite, pyrrhotite, sphalerite, chalcopyrite and galena. Minerals like bornite, arsenopyrite, tennantite and magnetite may be present in smaller amounts. The gangue is mainly quartz, but occasionally carbonate can also develop…

In our society today anxiety is a problematic disorder. It creates the need for much support and love from loved ones. This disorder have hit home in the sense that nearly every individual has a family member or friend with this disorder. Having to experience and endure the challenges of the onset of this illness can be stressful. Anxiety is very challenging with the behavioral conditions and symptoms that are related with this illness. Having to experience this disorder with a loved one tends…
