Related termsFrom Wiktionary under the GNU Free Documentation License. In chemistry, a mixture is when two or more different substances are mixed together but not combined chemically. The molecules of two or more different substances are mixed in the form of mechanical mixtures, solutions, suspensions, and colloids. While there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by mechanical means. Azeotropes can not, at least not directly. Mixtures are the product of a mechanical blending or mixing of chemical substances like elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup. Mixture refers to the physical combination of two or more substances the identities of which are retained. Mixtures are either homogeneous or heterogeneous. A homogeneous mixture is a type of mixture the composition of which cannot be identified. A heterogeneous mixture is a type of mixture the composition of which can easily be identified since there are two or more phases present. Mixtures are when two or more things physically combined. When things are chemically combined together it's called a compound. From Wikipedia under the
GNU Free Documentation License How many moles of O2 are in the mixture? Q. A gas mixture contains twice as many moles of O2 than N2. Addition fo 0.200 mol of argon to this mixture increases the pressure from 0.800 atm to 1.10 atm. Asked by georgie0515 - Mon Nov 19 06:56:00 2007 - - 1 Answers - 0 Comments A. The partial pressure of 0.200 mol of Ar is (1.10 - 0.800) atm = 0.30 atm. Thus the original 0.800 atm contains 0.800*(2/3) mole or 0.533 mol gas mixture of O2 and N2. Now, I do not understand what you mean by "twice as many moles of O2 than N2". If you mean "twice as many moles of O2 as N2", there would be 0.356 mole of O2 and 0.178 mole of N2. If, on the other hand, you mean "twice more moles of O2 than N2", there would be 0.400 mole of O2 and 0.133 mole of N2.

Q. Soybean meal is 14% protein; cornmeal is 7% protein. How many pounds of each should be mixed together in order to get 280 lb mixture that is 10% protein. How many pounds of the cornemal should be in the mixture? How many pounds of the soybean meal should be in the mixture? Asked by Chad S - Sun Apr 20 20:46:45 2008 - - 2 Answers - 0 Comments A. Hi, %(pounds of A) + %(pounds of B) = mixture %(pounds mixture) 14x + 7(280 - x) = 10(280) 14x + 1960 - 7x = 2800 7x + 1960 = 2800 7x = 840 x = 120 120 pounds of soybean should be mixed with 160 pounds of cornmeal to make a mixture that is 10% protein.
