by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

Potentiometric Titration of Sodium Carbonate Otieno O. Victor University of Detroit Mercy Quantitative Analysis Lab CHM 3880 Fall 2011 Partner: Edwin Gay Abstract The PH at each point during the titration of sodium carbonate unknown sample was determined. An Unknown sample of Na2CO3 was titrated with a standard HCL solution. In addition to titration‚ the pH at each point of titration was measured using PH meter. The % of the unknown Na2CO3 was 25.83% Introduction1 The purpose of this experiment

and these comprise only 20 kinds of amino acids in various combinations. These 20 kinds of amino acids are essential to the body. In addition to being the materials for proteins‚ they are used as an energy source for the body as necessary. Further‚ each amino acid plays an important and unique role in the body. The list below shows the role of each amino acid. | Valine Leucine Isoleucine | All of these 3 amino acids are called branched chain amino acid(BCAAs). They perform the important functions
