I can draw three characteristics from properties that gases have. Compressibility, expandability, and the way in which gases occupy spaces more than liquids or solids in a taken form. A tremendous example of this characteristic in which we use to describe compressibility in gases, is the way in which a 911 Porsche sports car works. A 911
Porsche sports works off an internal combustion engine(normally v8/ but in this case I'm talking about a particular four-stroke), in which “compresses gases” just as I was talking about. In order to operate, the piston in the engine pulls out of the cylinder to create a vacuum which draws a mix of gasoline vapor oxygen into the driving cylinder compartment. Then eventually seconds later, the piston then rotates pushing back into the cylinder compressing the gasoline/air type of mixture to a new volume, compared to the volume it had when the piston was rotated to the top of its socket. The typical car has a 9 to 1 compressibility ratio, but this porsche has about 7 to 1 compressibility, which can mean the gas to air mixture in the cylinder is compressed by a factor of 7. The second
Property I would like to outline in gases is expandability. Anyone who has walked into a bathroom where many people have just taken a number 2, have experienced the face that gasses expand to fill their container, as the air in the disgusting bathroom becomes filled with terrible odors of waste. Just as people smell during a formula 1 race event, characteristic odor of C2H5OH Ethanol rapidly diffuses through the race track as it makes it way through the cars and also is on the track of the pit stops. Gases expand to fill their containers, so it is safe to say that volume of a specific gas can be equal to the volume of it...

...hing is represented in moles, therefore ideal gas law must be employed to solve the volume or mass of bass involved in the reaction. For example, if I wanted to calculate the volume of NO2 produced from combustion of 100 g of NH3, by reaction 4NH3 +7O2=4NO2 + 6H2O. It could be solved by 100 g NH3 times 1 mol NH3/17.034gNH3= 5.871 mol NH3. But on another hand the chemical reaction is given in terms of moles, not grams, so therefore the ideal gas law must be employed to solve the volume or mass of the gas involved in the reaction. In using the same example as before, if I wanted to continue out the process: there is a 1 to 1 molar ration of NH3 to NO2 in the balanced combustion reaction, so 5.871 mol of NO2 will be formed. Using the PV=nRT to solve for the volume at zero degrees (273.15 K) and 1 atm using the gas law constant R=008206 times atm times K-1 times mol -1.
“Death is the only pure, beautiful conclusion of a great passion” (David Herbert Lawrence). Coretta Scott King was an inspiring person to women of all ages and races. However her death had an impact on everyone, she was seen as an idol, more importantly as a leader. Malcom X’s daughter Attallah Shabazz who is also Mrs. King’s most pride supporter addresses her remarks in her eulogy and engages the people at the funeral service for Mrs. King on the sorrowful day of February 7th, 2006 in Atlanta, Georgia. With hundreds of people, (mainly women) watching on TV or listening in the stands during this depressing time reflect and honor on the achievements and positive attitude she had on the community for others. Attallah Shabazz hoped that this event

to be done. This was to find out what amount of each liquid would be
In order to reduce emissions, modern car engines carefully control the amount of fuel they burn. They try to keep the air-to-fuel ratio very close to the stoichiometric point, when all of the fuel will be burned using all of the oxygen in the air. For gasoline, the stoichiometric ratio is about 14.7:1. However, this fuel mixture actually varies from the ideal ratio quite a bit during driving.
so they could compress the air at a much higher pressure so the engine can
The comparison between the vapour compression and vapour absorption systems are given in Table 1
Part A of the experiment, we were measuring the density of water. In this part, we measured by difference by measuring the mass of the empty graduated cylinder which was 46.35 grams and then added 25.0 milliliters of water to it. When subtracting by difference, our mass of the water was 25.85 grams. This was close to the measurements of the water added to the graduated cylinder. The density of the water was 1.0 grams/milliliters.
In my experiment, I will use an overall volume of 50 cm³ of 2moles of
