Typical ingredients in coffee are roasted coffee, sugar, cream, spice like cinnamon, and water. She has taught science courses at the high school, college, and graduate levels. Once this kind of mixture forms, you can no longer separate the individual ingredients again, thus ensuring that the mixture has now formed definitively and that all the substances are now uniformly distributed throughout. Each atom in the gold bar is identical to other atoms and they all have the same chemical properties. However, if the water is on the cooler side, the solubility level will reduce considerably. Each of the layers is called a phase. The composition of components does not vary from sample to sample provided the sample size is considerably large to the size of components.

The amount of salt in the salt water can vary from one sample to another. You can use a mechanical method to separate components of a heterogeneous mixture (e.g., sorting candies in a bowl or filtering rocks to separate them from sand). The four fundamental states of matter are solid, liquid, gases, and plasma. The Na+ and Cl- ions are completely dissociated from one another in solution and form electrostatic interactions with hydrogen and oxygen atoms in the water. You will notice 3 grams of salt does not contain 3 grams of sodium, nor is half the mass of salt from sodium, so 3 grams of salt does not contain 1.5 grams of sodium: Then the amount of sodium in 3 grams of salt = 39.3% x 3 = 1.179 g or about 1200 mg.
