UNIT 4

YouTube (January 19, 2011). http://www.youtube.com/watch?v=a-x0AJQ5zHQ

This video is about saving the earth and how were able to help clean up our communities. This relates to the unit, "Solutions and Solubility." The big idea this video focuses on is people have the responsibility to protect the integrity of Earth's water resources.

This video showed pictures throughout the whole clip while playing the song "A Beautiful Day" by U2. Most of the pictures shown throughout the video were horrible sites of polluted water and gave facts outlining that 45% of municipals water had been infected. Companies that dump their waste into local lakes and creeks, obviously do not understand the effects this waste has on the environment and the animals that live for the water. Ducks that swim in the water, fish that depend on freshwater sources and the organisms that strive for clean water are all at risk because of the infectious waste these companies dump out. Water is a limited resource. The world may be made up of 70% of water however, only 3% of that water is drinkable. Of that 3% about 68% is encased in ice caps, 30% is ground water and less than 1% is above the surface. In that 1% of water, 87% of drinkable water is in lakes whilst the remaining percentiles are in swamps and rivers.

Outlines Water Distribution Throughout The World

Simple solutions can be made. Whether these solutions are small or huge, they will effect the outcome of the Earth. The video outlined a number of different ways to help. Turning off your tap while brushing your teeth or large such as passing laws and bills through courts and lawyers. In this unit we learned all these things and continue to realize the effects that these effortless solutions have on the environment and that we can play a big role in saving an animals life. We also had a hands-on experience in performing titration's and dilutions. We role-played that we were searching for harmful chemicals in our water system to see if they existed.

UNIT 5

The image shown above, represents a sick earth coughing up what appears to be smoke. This is most likely due to the pollution we have created through out the centuries. The related unit is "gas and atmospheric chemistry." The big ideas within this unit is air quality can be affected by human activities and technology and people have a responsibility to protect the integrity of Earth's atmosphere. The uses of everyday items cause constant greenhouse gases to get release into the atmosphere.

The release of methane gases into the atmosphere from our backsides is enough that the world can handle, but the release of many of these 'farts' from the amount of cars that inhabit this earth and the amount of smoke released by companies with huge stacks is burning a hole through the ozone layer. Fossil fuel energy is the most dangerous kind of energy and our Earth's main source of energy is fossil fuels. Estimations by the Energy Information agency (2007) list petroleum (approx. 36%), coal (approx. 27.4%) and coal (approx. 23%) as the top three energy sources and amount to 86.4%of the worlds energy source. As a result of this non-renewable consuming our earth, scientists have started looking into renewable sources that produce much less environmentally friendly gases namely, electricity or harnessing wind energy.

With the increasingly amount of problems and deadly diseases such as: asthma, lung diseases and heart disease, the cleanliness of our oxygen is becoming more vital to surviving for future generations. The bigger the population gets, the more pollution is created and the thicker the smog in the air gets. An example of this was the Summer Olympics of 2008 in Beijing, China. The amount of people in china is extraordinary and as a result, a thick cloud of smog had surrounded the stadium. This is a problem to the world because wind blows this smog around the world and within days, it could reach North America. Cleaner energy sources are becoming crucial to the living organisms that have taken a domain on Earth.

UNIT 3

(January 18, 2011). http://nzic.org.nz/ChemProcesses/food/6D.pdf

This pdf document outlines all the chemical processes that occurs during baking. This relates to the unit, "quantities in chemical reactions." The big ideas within the unit that this document covers are relationships in chemical reactions can be described quantitatively and the efficiency of chemical reactions can be determined and optimized by applying an understanding of quantitative relationships in such reactions.

The amount of concerns and chemical reactions that occur during baking are tremendous and must be taken into account, otherwise a cake can become soggy and wet. Certain ratios have been invented to take this into account and to ensure a complete and tasteful final product is met. one good proportion that is used within baking a rising flour is one teaspoon of baking powder for every one cup of flour. Without this ratio, with a lot of baking powder, the cake would turn out disfigured and with too much flour, the cake would not rise at all. The overall size of the cake should be taken into account as well, since your ingredients determine everything.

Some chemical equations are listed within the document. The main equations are for baking soda and baking powder. Baking soda creates a strong base and as a result baking powder is used more often. Baking soda revolves on the release of CO2 and the equation is: 2NaHCO3 -> Na2CO3 + CO2 + H2O. Baking powder is baking soda with acid added in it already. Because of the neutralization, more CO2 is produced and the equation is: NaHCO3 + H(^+) -> Na(^+) + H2O + CO2.

Baking can be applied to the elements that were taught to us in this unit of grade 11 chemistry. different proportions of a chemical equation can effect the total outcome of the final product. This is why the mole ratio was founded. This allows us to figure out the limiting reagents and excess reagents. The limiting reagents allow us to figure out how much of the final product will be produced and how much chemicals we will obtain in excess. In baking, there is no limiting reagent or excess agent as all the ingredients are needed to create a final product whether that products turns out good or bad.

UNIT 2

E-how Blog (January 18, 2011). http://www.ehow.com/about_5434043_hybrid-vs-gasoline-vehicles.html.

This article is about the aspects on hybrid vehicles. They include: how hybrids work, the price ranges, Thee amount of variety in hybrids and their obvious fuel efficiency. This relates to the unit, chemical reactions. The big idea focused from this article is chemical reactions and their applications have significant implications for society and the environment. This article tells of the future of the car industry while making changes to decrease the amount of emissions a car exhausts.

A hybrid vehicle consist of two engines. an electric motor which provides energy to the vehicle under certain conditions (i.e idling) and a gas engine, smaller than the traditional gas engine found in gas-powered vehicles. A hybrid utilizes both by combining them for maximum power or by switching between the two engines to provide maximum efficiency. The use of a rechargeable battery pack provides power to the electric motor. The two main types of hybrid vehicles are a "mild hybrid" and a "full hybrid." A mild hybrid still relies on a gas engine however, their electric motor is able to recharge itself during braking or downhill driving. During idling, the gas engine can be shutoff and replaced by the electric motor. Full hybrids have the ability to run on one motor without the use of the other engine. No gasoline is used when the electric motor is sufficiently charged.

A hybrid vehicle has a higher initial cost than a gas-powered vehicle because of its duel engines and the need to redesign a current vehicle to hold these motors. Companies have been in the works to improve the profitability. New ways to make this happen are by improving the amount of savings that can occur from a hybrid purchase and by reducing production costs.

The hybrid vehicle is considered the green-car for many reasons. The obvious reason is that, it lowers gas emissions by shutting off the gas engine during up hill driving or driving at constant speeds for long periods of time. Also, the noise pollution that gas-powered cars give off; When an electric engine is running, it gives off next to no sound.

Performance-wise, a hybrid vehicle out performs a gas-powered vehicle in mileage by 20-30%. Because of a hybrid's rechargeable battery through braking and kinetic energy, this allows the hybrid to be able to last longer than a gas-powered vehicle. The amount of savings received over gas is incredible over a gas-powered engine and the tax benefits received from most governments allow hybrid users even more savings.

We learned about the applications that chemical reactions have in our daily lives and the effects the final product does to our environment. The hybrid is the future vehicle because of its green ability. Ever since, we learned the effects the gas-powered vehicles have on the very real global warming, the world has been trying to be more environmentally friendly by: planting trees and switching to an alternative power source. this alternative power source includes cars because the amount of emission we produce daily just by driving to and from work is extraordinary. the hybrid vehicle provides nearly no emissions and utilizes the power of electricity to power itself. When this hybrid vehicle becomes a national vehicle, the amount of gas emissions produce will reduce ten-fold!

UNIT 1

"To: Honourable Leona Aglukkaq - Minister of Health

Subject:Protect Canadians and our environment from harmful chemicals in personal care products

I am concerned about toxic ingredients in personal care products. Chemicals that may harm human health or the environment do not belong in products we use on our body and rinse down the drain on a daily basis.

I urge you to strengthen Canada's approach to regulating chemicals in cosmetics. As a place to start, Health Canada should follow the European Union's lead and phase out the use of chemicals that are known or probable human carcinogens, reproductive toxins, or mutagens in personal care products.

At a minimum, warning labels should be required on cosmetics containing any ingredients linked to chronic health hazards or harmful to the environment.

I'm trying to do my part as a consumer to choose safer products, but what we really need are smarter laws that protect human health and the environment from toxic chemicals in consumer product"

David Suzuki Foundation (January 16, 2011). http://action.davidsuzuki.org/cosmetics

_______________________________________________________________________

This letter, addressed to the minister of health, outlines the toxic effects that some cosmetics now use in their recipe to create these attracting aromas. It relates to the unit, "Matter, Chemical Trends and Chemical Bonding". The main idea from the unit that was applied here was "it is important to use chemicals properly to minimize the risks to human health and the environment." This letter shows that humans are starting to realize the effects that cosmetics have on their bodies internally and the environment.

Without the use of shampoos on our head, the oil that builds up would be dripping out the ends of our hair. The toothpaste we spit out more than once a day it necessary to strengthen the enamel and neutralize more acids in our teeth. However, the daily use of these items have the ability to damage our bodies internally. Many cosmetics have the chemicals to potentially cause serious diseases such as: cancer, asthma reproductive disorders and allergy attacks. Inhaling these smells is dangerous. you're just as probable to have the same, if not worse, effect than the person using the product. Thousands of people have rallied and protested to companies about using safer products and thus, this letter was emitted.

The effects that cosmetics have on our bodies is not nearly as bad as the effect is has on the environment. Powders used to cover up and imperfections growing on our faces, hairspray's used to make our hair more noticeable and attractive and spray deodorants used to make our bodies smell nice and attract the noses of other people are all good examples of an environmentally harmful products. All these products going into the atmosphere are having a very harmful effect on the ozone layer. Trees and seaweed can only clean oxygen so many times before dying. Many efforts are being done on conservation lands including school trips to plant trees.

In this unit we learned abouts the harmful ingredients put into our everyday lives. This, in turn, brought up a traditional project created by Mr.K. We were to look into one ingredient from three everyday cosmetics and this raised some questions. "Why is this ingredient within my product," "If this chemical is dangerous, why do i use this product so often?" This showed us the harmful effects that are put inside our "chemically-enhanced" products.

Chemistry is an infinite universe in its own right. There is known safe chemical formulas that create the same effect that these dangerous formulas do. Companies that create these dangerous products are in the business for money and not for the well-being of the earth we live in. What good is money without a world to live in?
