THE CHEMICAL COMPOSITION OF AQUEOUS SOLUTIONS (pp. 94-98) Electrolytes – forms ions when dissolved in water (or certain other solvents) and thus produce solutions that conduct electricity. Strong electrolytes – ionize essentially completely Weak electrolytes – ionize only partially Solution of weak electrolyte will be a poorer conductor than a solution containing an equal concentration of a strong electrolyte Brønsted-Lowry theory Acid is a proton donor Base is a proton acceptor H2O + HNO2 H3O+ +

1) The main function of secondary storage is to store programs and data when they are not being used. 2) secondary storage is used to store data that is not being used 3) The most widely used form of secondary storage is magnetic disks because they are nonvolatile. 4) They are portable‚ inexpensive‚ lightweight‚ nonvolatile‚ and easily accesible. 5) It must be formatted‚ formatting defines the disk surface and erases any pre-existing data. It also scans the disk for any defects. 6) 1‚ the recording

Malaya had been brought up many times. Then‚ in 1961‚ Tunku Abdul Rahman revealed his aspiration to form Malaysia. Malaysia was support to be made up of Malaya‚ Singapore‚ Brunei‚ Sarawak and Sabah. There were a few factors that contributed to the formation of Malaysia. The factor was to gain independence through unification. Out of five countries‚ Malaya was the only one to be free from the British rule after its independence on 31st August 1957. By joining Malaya‚ the other four countries could

Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece

Encoding‚ Storage and Retrieval: The Processes of Memory Memory is very complex and a little mysterious. There is a lot to know about the way one can organize a lifetime of memories. Research has helped clarify several missing elements in the traditional three-stage memory model. One can now understand the way information is changed as it is encoded‚ stored and then later retrieved. These three processes can be described similarly to the memory of a computer. The first step to remembering a piece

The Growth and Formation of Individual Ethics Personal ethics materialize at an early age‚ and evolve throughout a person’s life based on many internal and external influences. These internal and external influences form the basis for each individual ethical system and determine how that system will interact with all the other individual ethical systems in which it will contact and interact within and outside of the professional environment. Most individual’s ethical system will be similar but

constituent elements. The purpose of this lab was to test for law of definite proportion through determining percentage composition of each element in Magnesium oxide. I hypothesized that the composition mass of magnesium will be more than oxygen and this would be the result for other groups as well. My null hypothesis was that if the experiment is done accurately‚ the percentage composition of magnesium shouldn’t exceed 65%.

This can be compared to the actual prison wall. The prison wall surrounds the prison like the cell wall is a stiff wall that surrounds the membrane‚ giving the cell a rigid‚ box like shape. Another resemblance is between the vacuole and storage rooms. The storage rooms stores food‚ water‚ for the inmates to eat later like the vacuole stores water‚ food‚ waste products‚ and other materials. In addition‚ a correspondence could be between the mitochondria and the prison generator. The Prison Generator
