  • Rain Water Break Research Paper

    back high in to the atmosphere into freezing temperatures (This is an updraft). The drop begins to fall again gaining more moisture and getting bigger. This happens over and over again until the drop is big enough to fall down to the surface as hail. So we know what rain is like on our planet. What is it like on other worlds? Let 's take a trip to the first stop in our adventure, the planet Venus. Venus is Earth 's twin. It closely resembles the size of our home. Venus is the hottest planet in…

  • Contaminant Regeneration Essay

    for re-use. Some of these technologies generate liquid effluents, solid wastes, and air emissions during the regenerating process. The types of wastes, effluents, and wastes vary with the technology and processes used, and the environmental control methods [CEPA, 1994]. Liquid effluents are required additional treatments before they can be reused for cooling or discharged to a sewer system [CEPA, 1994]. Solid wastes generated from the regenerating process include various types of sludge (e.g.,…

  • Copper Cycle Lab

    In the first step of the cycle, about 5 mL of 6 M HNO3 were added to the beaker containing the 0.2471 grams of copper turnings. In the reaction that followed, the copper turnings dissolved as the solution turned green and eventually light blue accompanied by a small sizzle. The chemical reaction that took place here was Cu(s) + 4 HNO3(aq)  Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O. This was a redox reaction because oxidation occurs. This was proven from the reaction because copper was oxidized by the…

  • Melting And Physical Change

    powdery clumps. After mixing the two it changed into a light brown homogenous powder. When heated, the mixture began to change, the iron liquified and the sulfur began to rise. The color also changed, the bottom was black and the top was more yellow, which created a yellow residue around the outside of the test tube. A gas rose out of the top and between the yellow and black, a red, brown syrupy liquid was created. After cooling the red liquid began to sink and the yellow area looked wet, also…
