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. After all materials were gathered‚ we then had to do five different tests to determine what the powder material does. The first test was to see what the powder materials do in water. We had to add a scoop of each of

1. What is Chemistry? The study of the composition‚ structure‚ and properties of matter. The processes that matter undergoes and the energy changes that accompany these processes. 2. What is the formula for density? If I give you the density of a substance and the volume‚ you should be able to tell me the mass… Density = Mass/Volume 3. Compare and contrast intensive and extensive properties. Give an example of each. Extensive properties depend on the amount of matter that is present. Such

Abstract The separation of a Fe3+ and Ni2+ mixture was firstly investigated; followed by the determination of the Fe3+ and Ni2+ content (concentration) in the original mixture. It was found that iron was a yellow solution and nickel respectively had a greenish colour. Their original concentrations respectively were 0.03669 M for iron and 0.03159 M for nickel. Introduction Ion exchange materials are insoluble substances containing loosely held ions which are to be exchanged with other ions in
