Heroin and 6-monoacetylmorphine.
to convert the phthalic anhydride in to phthalimide, it is heated with urea at the temp. of 160 c with out using any solvent. phthalic anhydride + urea = phthalimide +water+ carbondioxide
It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
Chemical, it is reacting with the air
Acid reacting with metal
Reacting with oxygen to form an oxide is a chemical property.
Daminozide is made by reacting succinic anhydride and1,1-dimethylhydrazine.
to convert the phthalic anhydride in to phthalimide, it is heated with urea at the temp. of 160 c with out using any solvent. phthalic anhydride + urea = phthalimide +water+ carbondioxide
a paint binder or paint vehicle made by reacting coconut oil with a polyhydric alcohol such as pentaerythritol or glycerol and then reacting the resulting mixture of monoesters with phthalic anhydride
Chemical.
This is a chemical property.
Chemical change
always.
This is a chemical reaction, a chemical change.
Its a chemical change. its like an acid reacting with a base to form salt and water.
Yes.
It is a chemical property.
The chemical equation demonstrates the ratio of chemicals reacting and producing. Even though only minute amount of actual chemicals are reacting, the chemical equation shows which chemicals are doing what.
