Harmful Chemicals in our Environment Over the past century humans have introduced a large number of chemical substances into the environment. Some are the waste from industrial and agricultural processes. Some have been designed as structural materials and others have been designed to perform various functions such as healing the sick or killing pests and weeds. Obviously some chemicals are useful but many are toxic and their harm to the environment and our health far outweighs their benefit to

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

If You Ever Read This‚ Know That You Changed Me It’s so hard to only feel one particular emotion for extended period of time. Life is symmetrically separated by a thin line‚ one side is beautiful and the other is full of horror. My life is not in any way symmetrical. The pieces are not split equally‚ there is no pattern‚ only different shapes stitched back together to form one again. I would not let anyone help put back the pieces of my life together‚ because I thought I’d mold myself. That’s what

Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then
