secondary industries are textiles and electronics. A tertiary industry is in the service sector of the economy. Examples of tertiary industries are banking and education. ____________________________________________________________ _________ 2. How are product variety and production quantity related when comparing typical factories? Answer. Generally production quantity is inversely related to product variety. A factory that produces a large variety of products will produce a smaller quantity

Mining is the process of digging beneath surface of the earth and extracting minerals and other useful geological materials. There are two main categories that mines fall into; surface mines and underground mines. Surface mines are effective at extracting minerals and geological materials that are close to the surface of the earth while underground mines are designed to extract minerals and geological materials that are deep beneath the surface of the earth. One of the most common materials that

extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared directly by reactions of the hydrous manganese (III) oxide or by oxidation of the hydrous manganese (II) oxide with air or an oxidizing agent.(Pass‚1997) In aqueous solution Mn(III) is readily hydrolyzed Mn3+ + 2 H2O →Mn(OH)2 + H+ and

Parachute Experiment Aim: To investigate the effect of surface area on a performance (more the amount of a parachute better the performance) of a parachute. Hypothesis- More the amount of holes in a parachute‚ faster the rate of the fall. Variables: Dependent variable- The time it takes for the parachute to reach the ground. Control variables:Mass > Adding or subtracting mass from the load. > Clay can be molded around the load to increase mass. > Parts of the load can be cut off to decrease the

How does the amount of dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte
