Importance of chemistry in our daily life Importance of chemistry in our daily life Everything is made of chemicals. Many of the changes we observe in the world around we see that caused by chemical reactions. Chemistry is very important because it helps us to know the composition‚ structure& changes of matter. All the matters are made up of chemistry. In our every day like various chemical are being used in various from‚ some of those are being used as food‚ some of those used

Although I love science‚ I encountered more problems in this subject than any other. Recently‚ I was assigned a lab. The purpose was to let Copper Sulfate react with Aluminum and obtain Copper. Before the experiment‚ I set up the stoichiometric equation carefully‚ predicting the production of Copper using my assigned mass of Copper Sulfate. Additionally‚ I intentionally made Copper Sulfate an excess in my equation‚ since it would be dissolved in water and I would only have to collect Copper at the

Turn on electric mass scale (power button) and place a beaker on top of the scale. Make sure to only measure one beaker at a time. Wait till the digits on the screen slow down and stop at a number. The number it stopped at‚ that is the number you will right down in your lab book (that you will get out) as scrap notes. After you have measured each beaker
