A. A wood splint was soaked in the unknown solution for 5 mins and the splint was placed in the flame of a Bunsen burner. The flame was orange.
b. AgNO3 was added to the unknown and a white precipitate resulted. Upon addition of thiosulfate, the precipitate dissolved.
c. Oxalate was added to the unknown and a precipitate formed. The precipitate dissolved with 8 drops of HNO3.
d. Addition of hydroxide produced a cloudy solution.
e. Upon reaction with sulfate, a white precipitate formed.
f. Upon reaction with ferrocyanide, a precipitate formed.
g. Fe(salicylate) was added to the known and a brown/light red precipitate formed.
h. Addition with Ba(NO3)2 gave no reaction.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
