Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup

Next to water and air‚ soil is most essential to our very existence on the earth. Soils are the basis of support for most life‚ and a source of nutrients for marine life and fresh water. As a natural resource‚ soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity. Soil is basically broken-down rock materials and consists of decomposed rock debris and decayed organic

salts in saltwater dissolves into ions or charged particles that conduct electricity‚ they interact with the earth`s magnetic fields. The movement of saltwater due to tides that produces an electric current generates a smaller magnetic field”(Ayque‚ 10/3/16‚ Scientist Discover New Way To Image Earth’s Interior Using Magnetic Fields‚ paragraph 5 http://www.natureworldnews.com/articles/29550/20161003/scientists-discover-new-way-image-earth-interior-using-magnetic-fields.htm).

Soil degradation refers to the decline in quantity and quality of soil. Degradation of soil is done by erosion (wind and water)‚ biological degradation‚ physical degradation (referring to the over loss of structure and changes in permeability) and chemical degradation‚ this refers to acidification‚ declining fertility‚ changes in pH levels‚ salinization and chemical toxicity. Soil degradation affects not only the environment but also the economy as well as people. The effect that soil degradation

Attempting to dig a pit would have been toilsome and ultimately fruitless. Fortunately‚ while on a fieldtrip‚ my classmates and I came upon an archaeological dig site. It was basically a big pit‚ about five feet deep‚ that was perfect for our observations. There were obvious changes in the soil through the different levels‚ and the archaeologist on location provided
