Can you provide a picture
Im not so sure about that, but aspirin is an acetylsalicylic acid
Answer:
mixture
Explanation:
Chromatography separates components of a material based on their difference in polarity. Since the chromatography experiment resulted in more than one mark appearing, there must be more than one component in the material.
Upon standing for 24 hours, the liquid ink separates into its different components based on their differing properties, such as density or solubility. Since a pure substance is homogeneous and has the same properties throughout, the ink cannot be a pure substance.
Answer:
Most stars are rather simple things. They come in a variety of sizes and temperatures, but the great majority can be characterized by just two parameters: their mass and their age. (Chemical composition also has some effect, but not enough to change the overall picture of what we will be discussing here. All stars are about three-quarters hydrogen and one-quarter helium when they are born.)
Explanation:
We assume that is represented by A and is represented by B respectively.
According to Wilke Chang equation as follows.
where, T = absolute temperature = (273 + 37)K = 310 K
= an association parameter for solvent water = 2.26
= Molecular weight of water = 18 g/mol
= viscosity of water (in centipoise) = 0.62 centipoise
= the molar volume of oxygen = 25.6
Hence, putting the given values into the above formula as follows.
=
=
Thus, we can conclude that the diffusion of in water by the Wilke-Chang correlation at .
