Mixture is a combination of two or more substances that are not chemically combined. The substances are formed
together but no new substance is formed. A mixture can be of any form. It may be solid, liquid or in gaseous
form. Mixtures can be classified according to their appearance. Uniform mixtures or Homogenous Mixtures have
substances that cannot be recognized because solutes completely dissolve in the solvent while Nonuniform or
heterogeneous mixtures have components which can be identified easily.
EXPERIMENT:
Forming Mixtures
A. Materials:
Three glasses, water, teaspoon, flour, food color/soy sauce, cooking oil, pebbles/small stones
B. Procedure:
1. Half-fill the four glasses with water.
2. Put the food color/soy sauce in one glass. Stir. Label it as "Set A.
3. Put a teaspoon of flour in the second glass. Stir. Label it as "Set B".
4. Put a teaspoon of cooking oil in the third glass. Stir. Label it as "Set C".
5. Put the pebbles/small stones and the flour in a plate or petri dish…
Mixtures are created by physical means (mixing a substance with another; no chemical bonding); if so, can they be separated only by physical means?
There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample.
You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change.
Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the
entire sample, and that the sample is in a sealed box, so that no matter can enter or leave.

A solution is prepared by adding 39.0 g of potassium sulfate to 225 g of water, carefully heating the solution, and cooling it to 40C. A homogeneous solution is obtained. Is this solution saturated, unsaturated, or supersaturated? The beaker is shaken, and precipitation occurs. How many grams of potassium sulfate would you expect to crystallize out?arrow_forwardConsider two boxes with the following contents: the first contains 30 bolts and 30 nuts that fit the bolts; the second contains the same number of nuts and bolts with the difference that each bolt has the nut screwed on it.

- Consider two boxes with the following contents: the first box contains 10 blue paper clips and 10 red paper clips; the second contains the same number of each color of paper clip with the difference that each blue paper clip is interlocked with a red paper clip. Which box has contents that would be an analogy for a mixture, and which box has contents that would be an analogy for a compound?arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forwardSuppose someone emptied ball bearings into a container of salt. Could you separate the ball bearings from the salt? How? Would your method involve no change, be a physical change, or be a chemical change?arrow_forward
