Chemical Reactions- Sodium Hydroxide - 1555 Words

Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change, effervescence (bubbles), when light or heat given off, and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning), synthesis, decomposition, neutralization, single replacement and double replacement. A combustion reaction is a reaction with oxygen, and heat is evolved (given off). A common example of combustion is Hydrogen +Oxygen= Water Synthesis is a reaction where two or more substances combine to make a compound. An example of a synthesis reaction is Iron + Oxygen = Iron Oxide†¦show more content†¦The sodium oxide is then mixed with water to produce sodium hydroxide. Na2O + H2O = 2NaOH Nicolas LeBlanc, who found out a way to produce an alkali from sea salt, discovered the LeBlanc process. Another way to make sodium hydroxide is by adding lime (general term for various minerals where carbonates, oxides and hydroxides of calcium predominate ) to natron (a mineral salt mainly with the mixture of sodium bicarbonate, sodium chloride, sodium carbonate and sodium sulphate ) . This is also a synthesis reaction, as it combines 2 simple substances and makes one complex substance. Lime + natron = sodium hydroxide Sodium hydroxide is very important in the industrial, commercial and biological world. In the industrial world, it is used for the textile industry, making paper, making soap and making detergent. In the textile industry, sodium hydroxide is used for scouring the material before weaving. In the paper industry, sodium hydroxide breaks down the lignin in wood, to free the fibres that can be turned into paper. The soap and detergent industries use sodium hydroxide to make soap by the saponification (the reaction of a metallic alkali base with fat or oil to make soap ) process. Saponification is a traditional process used by the Arabs in the 7th century, and it is still used today. In the commercial world, sodium hydroxide is used to prepare food. For example, German pretzels are dipped in a sodium hydroxideShow MoreRelatedPrac Report-Precipitation785 Words   |  4 Pagesoccurs when two aqueous (soluble solids) solutions are combined and the reaction forms an insoluble solid. When in soluble solids are formed the process is known as a precipitation. An insoluble solid is a solid that cannot dissolve unlike a soluble solid. Therefore only insoluble solids can form precipitates. In the following experiment six solutions were mixed with each other (groups of twos) in test tubes to test which reaction will result in an insoluble solid. See method for more detail. It isRead MoreUses and Properties of Sodium Hydroxide663 Words   |  3 PagesChemical Symbol: NaOH What it means: Sodium hydroxide is made up of sodium (Na), oxygen (O) and hydrogen (H). The chemical symbols for oxygen and hydrogen come from their names. Sodium’s chemical symbol, Na comes from the Latin word Natrium which means sodium carbonate. What state we usually find it in and why: Sodium hydroxide is an odourless, white crystal solid at room temperature. This is because sodium hydroxide has an ionic bond, meaning it has a high melting point, above room temperature.Read MoreThe Ionic Reactionalization786 Words   |  4 Pages 1.

A lot of families have children that have their own personal computers. Video games are more popular than ever and most children have some sort of video game console in their home as well. Television has been in the modern family home for many years now. It is easy to assume that nearly one hundred percent of homes in The United States has at least one television somewhere in the house. Most families have multiple televisions throughout the house. You can also assume that cellular telephones are owned and used by every family in The United States. All of these advances in applied science have the ability to enhance the human development from an early age. All of these advances in applied sciences can also be a detriment to families interacting with one another. These advances in technology divide families from one another. Children and parents alike can sit and watch television for hours without saying a word to one another. Children who play video games all afternoon instead of face to face social interaction are affected by this. They tend to become more independent from societal interaction.

Help Save the Green Planet free essay sample

Do people want more green in the world? Then help save the planet and go green! Going green is an effective way of lessening consumption on natural resources that people use every day. One does not have to be a treehugger and change one’s lifestyle, just try to make a change in doing something different everyday to help save the planet. In the United States, Americans consume many resources and discard many wastes into the environment that affects all nature. If people want to live in a better place, then make the environment a better place to live. Some of the greatest threats that people dump into the environment are things that people use every day. Household items such as batteries and electronic phones contain dangerous chemicals, such as mercury, and if thrown out may leak into the soil and contaminate the groundwater and the foods produced. This is a very dangerous situation because once contaminated, it is difficult to purify once again. We will write a custom essay sample on Help Save the Green Planet or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It will become a threat not just to humans but other living organisms. To dispose of batteries correctly, recycle them in a proper recyclable place, and if possible, recharge the batteries so they last longer and also decrease the amount of batteries used. For cell phones, drop it off at a drop off center, or donate it to a special facility. Either way, there are many different ways that one could dispose of these items correctly and stop the contamination of the soil. Vehicles such as cars are also a threat to the environment because they release carbon dioxide and other toxic gases into the air. An alternate means of transportation that one may use to help the environment, is to consider a hybrid car, ride a bike, or a train to help prevent the increase of emitting gas out into the air, which causes the greenhouse effect and a waste of gas. The greenhouse effect causes the ozone layer to become thin, because it traps the gases in the air, such carbon dioxide, and causes the Earth to heat up. This in turn causes the ice to melt and temperatures to rise up, which is a threat to animals such as the polar bear. The polar bear’s only survival habitat is the ice, and without the ice it will perish. Therefore, taking an alternative way of transportation is also an act of going green, and a way to help decrease the amount of pollution in the air. Another threat to the Earth’s environment is also caused by the factories that emit pollution into the air and worsen the breathing environment. In the United States, and in China especially, there is much pollution in the air caused by industrial factories. The people in China are in danger by breathing the air, because it causes many deaths, cancer, and diseases from the pollution. Some people wear masks to help prevent breathing in the toxic air, but it is still unfortunately a deadly threat to one’s health. To help promote cleaner air, one could try to avoid products produced by these industries or help support other companies that use â€Å"going green† methods. With these ways to help prevent less pollution in the air, one could be able to live and breathe safely without the intake of harmful chemicals. Another effective way to help save the planet is also doing simple things in one’s home. During the day, try to turn off all lights that one does not use in the house, so that it would help to save energy. Instead, open the blinds of the windows so that light may enter the home. Fresh, clean water is also a very valuable resource and is slowly decreasing in the world. Therefore, when brushing one’s teeth, or taking a shower, turn off the water if not in use. Unplugging electrical devices when not in use also helps to conserve more energy, because by doing so, it reduces the demand for fossil fuels. For the benefit of the Earth’s natural resources, all these actions are helpful things that one can do to help conserve energy in one’s home. One may also recycle the materials and prevent waste on the land. That way, it helps to save the Earth’s natural resources and lessens the poisoning in the environment. For example, people could make a group to help the community grow more trees in the environment or help other facilities pick up trash. Some schools are also collecting soda cans, cell phones, and other recyclable items in their community. Since the green planet has provided humans with so many beneficial resources in one’s life, shouldn’t people in return and help make the world a cleaner and better place to live? Overall, making an effort and a difference in the community by doing these simple things in everyday life helps benefit the environment and the world. Going green is an effective way to help save the Earth’s natural resources and for the environment to become cleaner and a better place to live for all people.

The Securities and Exchange Commission free essay sample

A study of the origins and effects of the Securities and Exchange Commission (SEC) set up as a result of the Great Depression. When the American federal government set up the Securities and Exchange Commission to reassure investors that they might safely put their money into American companies after the Great Depression, it accepted its fundamental responsibilities to protect its citizens from at least some of the buffets of historical and economic change. This paper explores both those immediate and long-term effects of the establishment of the Securities and Exchange Commission. The SEC has been able to function most effectively when the administration in office shared this basic progressive stance with Roosevelt. It has fared considerably less well during those historical eras when the part in power in the White House has believed in the gods of market forces. Neither Ronald Reagan nor George Bush believe in the same way that FDR did that businesses should be constrained so that they are forced to act morally and for the public good.
