Experiment 5 – Percent Water in a Hydrated Salt Pre-Lab Hints 1. Note definition of deliquescent in the introduction. 2. See side notes for part A‚ as well as part 1 of Technique 15C (pg 27). 3. Mass of water in sample is the mass lost by heating (initial minus final). Water % is 100 times the g of water divided by the initial g of hydrate sample. 4. a. See step A1 in the procedure. b. A hot sample on the balance creates air currents and causes thermal expansion‚ both of which decrease

Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

Advantages and Disadvantages of Oil Sands Oil sands are a type of unconventional petroleum deposit. They are loose sand or partially consolidated sandstone that contains natural mixtures of clay and sand‚ saturated with a viscous form of petroleum. Natural petroleum deposits are reported in many countries‚ but are found in extremely large quantities in Canada; 70.8% of the globally estimated oil sand reserves are in Canada. Most of the oil sands of Canada are located in northern Alberta. They

The development of the oil sands is a highly contested issue. The Globe and Mail published an article about why the oil sans should be established. It states that Oil revenue is essential to the economy of Alberta and to an extent the economy of Canada. As a result the government backs the oil sands. CBC published an article on why oil sands expansion should be stopped. The article states that scientists and environmental groups are pushing for no new oil sands to be developed because of the detrimental

Unmasking the Iron Veil The Salem Witch Trials and McCarthyism are two very different time periods in which the persecution of others‚ based on religion or party affiliation‚ happened. These two eras occurred two centuries apart‚ yet both are very similar. The constant fear and chattering of rumors induced hysteria and paranoia within both societies. It makes you wonder if we‚ as a society‚ can accept others who are not described as normal? Or can we even accept those who are different and not judge

benefits that the tar sands bring to Canadians‚ they are destructive to the environment. One of the biggest disadvantages of the oil sands production is the negative effects it has on the earth’s environment. One of the largest sources of carbon dioxide emissions in Canada is due to the tar sands since they require a lot of energy to be produced. The energy needed in this production is to transport the sand‚ then break it apart and then heating water to separate the bitumen from the sand. All these activities
