the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II) nitrate

According to the 55-data collected with the result in a response rate of 100 percent‚ there are some respondents agree while the others disagree as will be discussed by being break down according to its variable. First construct is system usefulness. This variable consists of eight questions as shown in Table 3.1. Based on data in figure 3.1‚ the result on the first question shows that 6 out of 55 (11%) are feeling very satisfied with the ease of using this system‚ 10 out of 55 (18%) are satisfied

For example the movie tried to convey the assumption that humans only use 10 percent of the brain which is misleading. The correction is this fact: it’s not that we use only 10 percent of our brains‚ rather it’s that we only understand about 10 percent of how it functions. As stated by the Scientific American article published February 7‚ 2008‚ "Do People Only Use 10 Percent of Their Brains"‚ “the ’10 percent myth’ is so wrong it is almost laughable‚ says neurologist Barry Gordon at Johns Hopkins

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

Apache Indians My overall first impression of this oil on copper painting called Apache Indians by Ramon Torres in 1780‚ was the view of the 18th century lifestyle as apache indians. This painting depicts a great picture of their daily life and culture. The male out hunting to provide for his family while the female is providing for the family by nurturing the child. This painting leaves me wondering what the male is about to shoot the arrow at. I see the deer in the background‚ but it appears that
