Red had no reaction. Dilute HCl: Bubbles up and fumes form, the zinc became darker in color. Dilute NaOH: None Substance: MgO Color: White Odor: Yes Effect of Heat: None Solub.

or Reaction w/cold H2O: terminate water turned white. Solub. or Reaction w/ bitter H2O: MgO separated from water. Litmus test: Red turned blue and blue had no reaction Dilu te HCl: Fizzes and way turns yellowish whil! e bubbling the back to white. Dilute NaOH: Dissolves and sum total became a bit thick Substance: CuCO3 Color: dark- one thousand Odor: Yes Effect of Heat: Turned into black pulverize Solub. or Reaction w/cold H2O: No reaction. Solub. or Reaction w/hot H2O: No reaction Litmus test: No change on blue or red. Dilute HCl: Bubbles up, does not dissolve, antecedent turns green Dilute NaOH: Turns navy blue Substance: Cu(NO3)2 Color: Blue Odor: Slight odor. Effect of Heat:...If you want to film a wide of the mark essay, order it on our website: OrderCustomPaper.com
