Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group.

Paragraph 1 - Compare and contrast the crystal structures and crystal chemistry of quartz‚ α-FePO4 and β-FePO4. Both α-FePO4 (space group: P3121) and α-quartz (space group: P3121 and P3221) belong to the trigonal crystal system‚ while β- FePO4 (space group: P6422) and β-quartz (space group: P6222 and P6422) belong to the hexagonal crystal system. At relatively low temperature‚ FePO4 is tetrahedral in structure. This is similar to the tetrahedral structure of quartz. As temperature increases‚ the

The social-emotional‚ cognitive and physical benefits of physical activity During childhood our body and mind changes very fast. I believe that nowadays parents focus more on the brain developement of their children than their physical activity. When I was a little girl - over 20 years ago - we spent most of our time outside playing‚ running and enjoying fresh air and being in movement. Physical activity of children can secure them health and well being in their adulthood as well as teach

Chemistry 5B Have you ever pulled a muscle? Are disabled? Had a broken bone? Been in a terrible car accident? Well‚ then you would probably know what physical therapy is. Physical therapy is where a physical therapist examines‚ tests‚ treats‚ and prevents injuries to your body. A big bonus for this occupation is it is one out of many career choices in the medical field‚ so in that case you know that a physical therapists gets a well-earned‚ good paying salary‚ but you have to go to college first

ingredients that most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide

Physical therapy has been in my life several times recently because of the numerous amount of injuries that have been piling up from football. Football is a grinding sport that requires physical contact every single day. This routine of bodies slamming into each other lasts for about three months every year but the after effects are felt long past the athlete hangs up his cleats. Athletes are sometimes left with debilitating injuries and that is when a physical therapist comes in to relieve some
