Use Of Green Chemistry For The Reduction Of Air Pollutants

Case Background: - In transportation industry, one of the biggest challenge is how to deal with carbon dioxide emissions and how to reduce the energy. According to the Natural Resources Canada, one third of the greenhouse emission is because of transportation industry.

Problem: How is the height of the geyser affected by the number of mentos added to the Coke?

In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of

The hypothesis about the CO2 angle will change the speed of the car was, rejected. The hypothesis was that if a Pinewood derby car had CO2 inserted at a 20 degree angle, then the 20 degree angle would work best because the angle would keep enough thrust power and keep the car on the track. However, the 20 degree angle was the second best because the 180 degree angle had more thrust power to it then the 20 degree angle. The control group was the 180 degree angle and it’s average was 1.33 second. The 45 degree angle was the longest with an average of 2 seconds. The 20 degree angle or second experimental group had an average of 1.67 seconds. I got these results because each angle that got farther from strait started to lose the amount of thrust that the 180 degree angle had. So if I tried it with a 90 degree angle then the car wouldn’t be moving at all.

Students will place a potato cube into a test tube and add 3 ml of H202 into each tube. Then students will wait one minute and record the height in cm of the bubbles and rate how rapidly the solution bubbles on a scale of 0-5. (0=no reaction, 1=slow,……. 5= very fast.)

This experiment has, in fact, proven my hypothesis to be incorrect, after looking through the results, I now understand why. My hypothesis stated that

Then we inverted the tubes so an air bubble would form in the little tube that is now upside-down. Now that we know what to do, we marked the little tube 2/3 full. One tube was filled to that line with glucose solution, another with fructose solution, sucrose solution and the last one with water. Next, the little tubes were topped off with a yeast solution. Then we slide a big tube over the little one and completed the inversion, this is done for every little test tube. After they are all inverted our group measured the bubble present at the top of the little tube. Then we put all of the inverted test tubes into a hot water bath for 20 minutes. After 20 minutes we took the tubes out and measure the air bubbles in the tubes. Next, we recorded the data calculated the net change from the beginning of the experiment to after the hot

The purpose of this lab is to find if the mass changes when you galvanize and put a penny in the flame of a Bunsen burner introducing it to heat. In this lab, you galvanize eight pennies to silver and then heat up four of the silver pennies and make it into brass with the Bunsen burner. The independent variable in this lab is the penny because we have control over of what kind of penny we use rather it be new, old, dirty, or clean. The dependent variable in this lab is the mass of the penny because we are measuring the mass of each penny. Finally, the constant in this lab is the sodium hydroxide because; we use the same amount throughout the whole entire lab.

The purpose of this lab was to experimentally and scientifically ascertain the percentage of oxygen in Chem B at Woonsocket High School. It was hypothesized that if the percentage of oxygen is measured experimentally in Chem B at Woonsocket High School, then it would be higher than the percentage of oxygen in dry air, which is 20.95%, because the air is not dry due to moisture in the air from people breathing and the altitude of where the experiment takes place may affect it as well.

The purpose for this investigation is to examine what car I will drive when I am 35. In today's modern day society, we rely on transport to take us from point A to point B. As good as it sounds it is bad for the environment. Not only burning fossil fuels to power our cars, it also affects your health and wellbeing, but it also damages the atmosphere. Naturally, the atmosphere has a thin layer to keep the earth at a certain temperature (Greenhouse Effect.) The carbon monoxide that is admitting from the exhausts of our cars, busses etc are unbalancing the chemicals within the atmosphere, causing the Earth to become warmer and warmer by the year. I will decide which car i will drive when I am 35, by using a thing called the DMM (Decision Making

The main purpose of this lab is to determine whether or not the number of carbon molecules relate to the amount of energy emitted measured through the temperature change over the course of 2 minutes. The main three tested fuels are fuels methanol (CH3OH), ethanol (C2H5OH), propanol (C3H7OH). Based on those formulas, Propanol alcohol has 3 carbons, Ethanol alcohol has 2 carbons and methanol has 1 carbon. Based on the hypothesis mentioned above “If the number of Carbon molecules in the fuel increases, the amount of energy over 2 minutes is going to increase”. Based on the data shown above, propanol fuel had the most temperature change meaning that it burned with the most energy. Following that is ethanol fuel having the second greatest temperature

The scientist’s main goal in this experiment is to see which metal will conduct the most thermal energy out of the three. The scientist will try and find a clear answer to this problem by placing two cups of water one cold and one hot to see which metal transfers the most

The transport sector is one of the main global consumers of fossil fuel related energy in the world. Unfortunately fossil fuel is non-renewable source of energy and the production of oil has been fluctuating in the recent past. At the same time, combustion of petroleum related fuel release greenhouse gases such as carbon monoxide and carbon dioxide that destroy the ozone layer and result to further environmental degradation. Therefore to work

Air, is one of the most substantial source to mankind and our planet. While it exists, so does everything else along. However, in today’s epidemic, there has been certain factors that have increased in understanding whether the air we breathe today is healthy or not? Is it doing more harm than we thought? In other words, the health risks against air pollution have risen in the past few decades; all from what you may ask? Well, it could be for various factors and evaluations; either environmental or materialistic. Pollution is a major public health crisis in the world. (Friis, 2012). This is one of the conflicts that contribute to various aspects of an individual’s life, whether they may realize it or not. In this paper will include the sources that cause pollution with the effects it cause as well as policies on the regulation of air pollution.

Pollution is a major problem globally and it becomes greater as the human population continues to rise exponentially. One of the major problems with increased population is higher waste production, which creates increased air, soil, and water pollution. To resolve this problem waste reduction must be of primary importance in preventing and reducing pollution. Waste management can be an expensive undertaking if not managed correctly so sustainable practices must be addressed. While pollution prevention and reduction programs can be expensive if not managed correctly, waste reduction is essential for the reduction and prevention of pollution.
