Name of gas: Nitrogen Dioxide
Gas characteristics: The gas seems reddish and brown. The gas is really toxic ]]> 2017-05-10 19:13:20 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103004 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103086 2017-05-10 19:13:44 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103086 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103112 We had the cooper in the tube, so we had put the nitric acid, only there drops, and we had introduced the dill on to the tube.
In a moment thid had done reaccion, and the liquid started to change the color. The dill start to chance it green color for a brown color, it's like the nitrogen dioxido reacts with it and this die. It smells very bad, and the tube turno on to yellow, and it's hot
CHEMICAL REACTION:
Cu + 4HNO₃ --> Cu(NO₃)₂ + 2H₂O + 2NO₂]]> 2017-05-10 19:13:52 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103112 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103138 Cu+HNO₃]]> 2017-05-10 19:13:59 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103138 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103166 tube, dill(green plant), ]]> 2017-05-10 19:14:07 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171103166 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171124283 Reaction of cooper with nitric acid and dill]]> 2017-05-10 21:23:15 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171124283 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171194712 2017-05-11 09:02:57 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171194712 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171194883 2017-05-11 09:03:52 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171194883 e_chemia https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171604775 https://drive.google.com/file/d/0B5LeWDEILDWEZE5JeVhxbzMwNWM/view?usp=sharing]]> 2017-05-13 09:26:44 UTC https://padlet.com/e_chemia/5qs9a3yic4kt/wish/171604775
