Water vapor

colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide (C3H6O, PO) with the presence of excess water and a small concentration of catalyst. The catalyst that plays the role in this reaction is the sulphuric…

things play a big part in the water cycle because they pull water from lands soil, which is a form of inhaling and exhaling water vapor so it rains forming a cycle. This cycle regulates the ocean chemistry by taking carbon out of the atmosphere. The ocean has chlorophyll concentrations and this is where organisms live. In areas where there is a cold water current the chlorophyll concentration is higher which stimulates phytoplankton. Cooler temperatures well up the water from way deep in the…

From the data given in Table 1, there are a total of four mixtures present in the whole activity. This is because the main mixture which is the salt, sand, chalk, and water mixture can’t be separated using only one separation technique; it should be separated by parts. First, a filter paper was used to separate the salt and water from the chalk and sand. is the filtration process, a separation technique using a filter paper to separate solid particles in a liquid. Second, acid dissolution, using…

control group, containing just the water and oxygen. The second jar would contain no water, while the third…

bodies of water, or put at treatment facilities that do not dispose of them properly. Now in turn, there are an abundance of areas where families do not have access to any facilities where they can relieve themselves, and due to this must often defecate in the open. These two major problems can often result in the contamination of water that people use as a source of drinking water. Through this process, an abundance of diseases reek havoc in the water. Once the disease is present in the water,…

Water exists in all three physical states only on planet earth, the only planet where life exists in the whole of universe. Water supports life on earth due its unique physical properties such as density, temperature variation, reflectivity, surface tension, specific heat, boiling and freezing points, as well as its chemical properties including its polar nature, dissolving ability and capacity to act both as an acid or base. The exceptional physical properties are all attributed to water’s…

four pairs of goggles and four sandwich bags. Make sure there are paper towels and trash bags at the ready. Demo and discussion: To introduce the idea of physical versus chemical change fill one flask with water and another flask with vinegar. Ask the students if they know which is water and which is vinegar just by their…

Land, water, air, etc. are was is being polluted by everyday garbage. “Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use” (Bradford). Land and soil are the ground to which garbage reaches first and even sometimes the soil is contaminated by…

understand. Understanding this concept was crucial to Mark Wattney’s survival as he did not have any water and desperately needed to find or create it. Of course, Mark Wattney would not have been able to find any water on Mars, and even if he could, it would not be sanitary. This meant he had to make it by bonding hydrogen and oxygen molecules. This process allowed Mark Wattney to create 600 liters of water that he would have otherwise died without. A hydrogen bond is the electromagnetic…
