A reflux condenser was assembled using a 25-mL round-bottom flask, hot plate, and aluminum block. It was equipped with a drying tube filled with calcium chloride to control vapors. Approximately 2.5 mL of isopentyl alcohol was massed and placed in the round-bottom flask that contained a stir bar. Using the same graduated cylinder, about 3.5 mL of glacial acetic acid was added to the flask. A calibrated Pasteur pipet was used to add 0.5 mL of concentrated sulfuric acid to the flask and the flask was mixed immediately. The flask was connected to the apparatus and covered with aluminum foil to help retain heat. Using rubber tubing, water was circulated into the lower attachment and out the top attachment and the mixture was brought to a boil. After heating under reflux for 60-75 minutes, the flask was removed from the heating source and left to cool down to room temperature. The reaction mixture from the flask was transferred to a culture tube and 5-mL of water was added. Upon addition of water, careful shaking, and occasional venting, the phases separated and the lower aqueous layer was removed and discarded. Using the same procedure as explained above with water, 2.5 mL of aqueous sodium bicarbonate was added and the lower aqueous layer was again removed and discarded. The same procedure was repeated one last time with 2.5 mL of saturated aqueous sodium chloride and the lower aqueous layer was removed and discarded, leaving behind the crude ester. The crude ester was transferred to…
We placed the zinc inside the beaker and slowly poured the hydrochloric acid into the beaker. As soon as the acid entered the beaker, there was a sizzling sound and bubbles started to form as we add more of the substance in. When the bubbles were forming, we could see a steam of gas coming out of the beaker. After 10 minutes, we noticed bits of zinc were floating on top of the hydrochloric acid and lining the beaker. I lifted the beaker and felt the bottom and it felt warm, which meant the reaction was still happening. After 20 minutes, we added water into the zinc and hydrochloric acid to stop the reaction and we observed a slight cloudy colour (still clear) forming as we slowly pour the water in the beaker.…
5. A) The washes that are performed in part B are necessary because the RTILs are often contaminated with halide slats such as KBr, which would cause the RTIL to be cloudy. In order to remove the halide contamination washes must be performed until the water does not result in cloudiness and is pure.…

The likelihood of an injury from this hazard is high as people could trip over it, maybe rushing to an emergency and the chair is blocking the way and causing a risk to staff and patients. The severity of injury is that someone could break/fracture a bone depending on how hard the fall is or the age/health of the patient. However we understand that some people need to be transported by wheelchairs as they cannot walk from a leg injury or they may just not be able to walk very far from where they were coming from. A porter may have left the wheelchair just in case an emergency occurred and we needed to transport someone quickly to a place who couldn’t walk/ walk far. The wheelchair could also be a hazard to children who decide to play on them as the brakes may not be on which would cause the wheelchair to move whilst a child was on it. This could mean that a child would end up falling and the wheelchair falling over causing another risk from the wheelchair being left…

After I attended all three Joe Stone’s events that happened on Ithaca College Campus. The first event holds at 5 to 6 pm Wednesdays, Sept 20 on the Old Fieldhouse across the street from main entrance of CHS. This first event of Joe Stone was about Outdoor Gear and Transfer Demos. From this event I learned and saw how difficulties life of disable to be independent on such as to use a toilet, to sit on wheel chair, and to get on a carStone mentioned and demonstrated how tough his life was and is without having proper access to technologies that met his problems. For example, Stone said after I became parahegia and I had arduous time to get a proper chair for my waste products to release. Another, example was that Stone stated having a small wheel that he can attached or unattached on his wheel chair when he need to go up hill or down hill. Stone explained and showed us how much a this little attachable wheel can make easier his life. Stone’s experiences of been a wheel chair person had hard time to run up on hill with their wheel chair because most wheel chairs have only two big side wheels. However, the little attachable wheel can make problem little bit smaller…
Kenneth Littleton Crow, a handicapped comedian, was my favorite comedian from the “Able to Laugh” comedy video. In his skits, Kenneth brings up wheelchair accessibility as well as interactions between disabled and non-disabled people. He jokes about how people do not always want to look at him while talking because they are uncomfortable or, how they do not know what to say to him because they feel bad for him. In the video Kenneth stated, “If they just stopped for a minute and thought well…you know maybe they’re not any different from me” (1:54). I completely agree with his message of breaking down former attitudes, building up feelings of mutual respect, and providing knowledge of life with a disability is like.…
As my partner and I maneuvered around campus, we came across various barriers which would hinder the best performance of an individual in a wheelchair. For example, in Birch Hall we attempted to access the available study rooms, but the doors to the study rooms are made of thick glass, making the process of opening the door extremely difficult. Moreover, we traveled from the Birch building to the Hickory building, entering a steep path. We identified that a person in a wheelchair could potentially lose control as a result of the path’s downhill nature. In addition, when we reached the Hickory building, we found that the restrooms had no doors. Although, at first, this would appear to benefit an individual with a wheelchair, the walls curved…
Once an individual has had a bad experience while carrying out a task, it diminishes their confidence and self-worth and makes the task seem impossible to achieve. When a person who has no perception of disabilities makes an aside of how someone in a wheelchair, for instance, could ever do something like climb a mountain, for the wheelchair user with a low feeling of worth and achievement this sort of comment makes even more of a barrier.…
The restaurant I picked was very accessible for wheelchairs. Unfortunately, the soap dispensers were to high up. When thinking about being in a wheelchair I could only imagine the amount of frustration they must go through especially if a restaurant or any place isn’t too accessible. Everyday is a struggle for them and after doing this assignment I wish I could do something so that all places are more handicap friendly. Doing this assignment was stressful knowing there are a lot of requirements but my heart goes out to all persons in a wheelchair because I know how frustrating it can…

Some people that have disabilities may have problems accessing health care. For example, the entrances to some GP surgeries don’t have very good access for individuals that use wheelchairs. If a wheelchair user has to open two to three doors before entering the waiting area this will act as a barrier. The wheelchair user does not want to depend on others to do things for them; this makes them feel incapable of doing things for themselves.…
Losing mobility in society is challenging, but overcoming those challenges can be accomplished. Anjali Forber-Pratt had a dream to race in a wheelchair in the Olympics, she achieved that goal and won. Taking what you were giving and make the most of it is exactly what she did. She inspires people everyday to never give up and that they can do anything they set their heart on. Her parents were criticized based on the ethical perspectives of others for the way they treated her as a child. When she fell out of her chair, her mother would not pick her up. Instead she would encourage Anjali to pick herself up because one day her mother will not be there. Her mother was strong and wanted her to have the best life, teaching independence over dependence was the way to ensure…
This exercise was actually really difficult. I have learned a lot by participating in this activity. I have done activities in my past work experience and put myself in other people’s shoes, to see what it was like having disabilities.…
