Mixtures can be classified as homogeneous or heterogeneous . Mixtures are composed of substances that are not chemically combined.
Homogeneous mixtures are solutions. The components of a solution are evenly distributed throughout, so that every part of the solution is the same. The components that make up a solution include one or more solutes dissolved in a solvent. Solutes can be solids, liquids, or gases, and solvents can also be solids, liquids or gases.
Brass is an example of a solid/solid solution, saline solution is an example of a solid/liquid solution, diluted ethanol is an example of a liquid/liquid solution. There are many examples of solutions. The components of a solution can be separated by physical means, such as distillation, evaporation, and chromatography, among others.
Substances that exist in solution almost completely as ions are called strong electrolytes. Therefore, the answer is C.
Answer:
exponents
Explanation:
The exponents in scientific notation should be added when multiplying, and subtracted when dividing. The exponents need to be the same so the leading numbers can be multiplied or divided. The result has the same number of decimal places as the least precise number.
