C7H16 (l) + 11O2 (g) 7CO2 (g) + 8H2O Heptane + oxygen carbon dioxide + water * Takes 11 molecules of oxygen and 1 molecule of heptane to make 7 molecules of carbon dioxide and 8 molecules of water 19. a) A reason for this trend is that oil deposits were being found all around the world during the time period between 1910 and 2000, therefore, there was an increase in production of oil over those years. ) This trend isn’t sustainable because most of the readily accessible oil deposits in the world have already been discovered therefore, since oil isn’t unlimited nor renewable, oil will eventually run out. c) Instead of driving a car to work, we could ride a bike. If biking isn’t possible, we could take public transit. Still, if someone is unsatisfied with these options, we could try buying a hybrid or electrically run car. (If we had the money) 20. 21. a) 1-ethyl – 3-methylcyclopentane b) 4,4-dimethyl-2-pentyne c) trans-3-heptene 22. To determine whether an organic unlabelled liquid is saturated or unsaturated is by dropping a small amount of iodine tincture in the liquids. Should the iodine color dissolve, then a reaction has taken place meaning that the liquid is unsaturated. Should the iodine color remain, then there has been no reaction meaning the liquid is saturated. 23. 24. a) Oils spills are easier to clean than TCE because it floats in water and therefore is easier to locate and clean and it doesn’t get into our groundwater. TCE, on the other hand, sinks into our groundwater and therefore more difficult to separate and clean. ) TCE can cause damage to our central nervous system and in a larger exposure causes headaches, dizziness, and confusion and in continued exposure can cause unconsciousness and eventually death. Along with damage to the nervous system, TCE can cause damage to the liver and kidneys. The ban of TCE is justified because should some be leaked into our groundwater; a large threat is posed onto many people’s health. 25. a) 1,2,3-tribromo-1-propene b) 1,2 butandiol c) 1-fluoro-4-methyl-3pentanone 26. 27. 28. CH3 – CH = CH – CH2 – CH3 + H2O CH3 – CH – CH2 – CH2 – CH3 l OH 2-propene + water 2-propanol 9. 1-Propanol has a hydroxyl molecule therefore it makes hydrogen bonds with other 1proponol molecules. Propanone only makes dipole-dipole bonds with other same molecules therefore its boiling point should be less than 1-propanol. 30. a) 4,4-methylhexanoic acid b) 3chlorobutanamide c) propylheptanoate 31. 32. 1- CH3CH2CH3– london forces 2 CH3 – C – CH3 ll Dipole-dipole O 3 CH3CH2CH2OH – hydrogen bonds The boiling points of these molecules is thanks to their intermolecular bonding. Since london forces are the weakest of all, CH3CH2CH3 has the lowest boiling point. Dipole-dipole atractions are stonger than london forces however weaker than hydrogen bonds, therefore , C3H6O has a higher boiling point than propane but lower boiling point than CH3CH2CH2OH. 33. When it comes to environmental issues, plastic and plastic bottles are always a concern. Their material is foreign to nature and therefore hardly decomposes. Although it contributes to pollution, a ban on bottled water would not be the solution. Should a ban be imposed, consumers would opt in buying other bottled products instead of water. Consumers would be more prone to instead buy pops which are unhealthy. Water, on the other hand, is healthy and quite safe to drink since it’s regulated under the Food and Drugs act in Canada. Therefore, bottled beverages would continue to be bought and plastic bottles would continue to harm our environment and ourselves. Both bottled and municipal water meet the health and safety standards considered to be safe. Although the costs of bottled water are greater than municipal tap water, the people who buy bottled water are those who can afford to do so, so costs shouldn’t be a reason for implementing a ban. The major implication with bottled water is the effectiveness of recycling and the energy required for recycling. In the US, 90% of the energy used was lost through the production process while generating large amounts of CO2 and polluting the environment with other types of waste. In this way, recycling is proving to be more of a hazard than a benefit to the world. Also, recycling isn’t 100% efficient; not everyone recycles and therefore bottled water still ends up in our landfills. Plastic bottles continue to accumulate in our landfills. In the US, the rate of recycling has remained at 27% over decades. A ban isn’t what should be implied by the government. What instead should be done is the government should invest in educating its people. The slogan is â€Å"reduce, reuse, recycle†. Society seems to be only preoccupied with the third method and forgetting about reducing our waste through reusing it. Throughout the world, the public should be informed of the importance of reusing their materials so that the waste isn’t actually waste. A bottled water ban without educating anyone would result in people choosing an alternative that would equally harm the environment.
