Red had no reaction. Dilute HCl: Bubbles up and fumes form, the coat became darker in color. Dilute NaOH: None marrow: MgO Color: White Odor: Yes Effect of Heat: None Solub.
or Reaction w/cold H2O: dissolve water turned white. Solub. or Reaction w/hot H2O: MgO isolated from water. Litmus test: Red turned blue and blue had no reaction Dilute HCl: Fizzes and center of attention turns yellowish while scintillating the back to white. Dilute NaOH: Dissolves and snapper became a bit thick Substance: CuCO3 Color: Green Odor: Yes Effect of Heat: Turned into down in the mouth powder 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 naval forces blue Substance: Cu(NO3)2 Color: Blue Odor: Slight odor.
