What relationship exists between a homogeneous mixture and the number of phases in the mixture? "I always have good luck on my side.". Concrete is a mixture because we can actually attain all the raw materials back from the hard concrete. A solution is a specific term that describes an even or homogeneous mixture of a solute, the substance being mixed, in a solvent, the substance that is in a greater amount in which the solute dissolves. 1 It was easy for me (uzupenij). 4 What is are the reasons why some other solutions mix and do does not mix together?

The first sip of Coca-Cola tastes the same as the last, which implies that the composition of ingredients inside the bottle is uniform throughout; however, in some cases, if the bottle is left open for some time, there can be a variation in taste due to the oxidation of the drink. Mixtures can be separated by physical methods. Under the sink there are cleaners bleach (sodium hypochlorite dissolved in water) and ammonia glass cleaner (ammonia gas dissolved in water).
