succeed from rags to riches and we already proved that to the world. From any kind of liquids that contains electrolytes‚ we can produce electric current out from it. Following an experiment from the Mesopotamians and today’s modern‚ “fruit battery”‚ we have constructed a simple machine that can be used at any time of need. Background Of The Study A thorough research for an exemplary Functional Investigatory Project that could be used as an inspiration came from the media such as

interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example‚ in the electrolysis of brine to produce hydrogen and chlorine‚ the products are gaseous. These gaseous products bubble from the electrolyte and are collected 2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2 A liquid containing mobile ions (electrolyte) is produced

Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive

Lemon Battery creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. Batteries consist of two different metals suspended in an acidic solution. Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED. The picture at the top

Elena High School‚ Marikina City Summary All people need energy in various forms such as heat‚ light‚ sound‚ etc. to sustain their everyday lives. Although these various forms of energy are equally needed by people‚ not all of them are always available‚ especially the energy needed to power up their main appliances which is electricity. Due to the inevitability

exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions present in the solution but

The board needs to decide what should be done to turn Duracell around and restore Gillette to a dependable financial performer. 2. How is the battery industry (you can use five forces analysis to answer this question)? Has it been changing? If yes‚ how? Overall‚ the industry is very attractive. New entrants realize the potential of snagging a piece of a highly profitable industry that produced
