Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

How much fossil fuel we add to our cars and meanwhile‚ how much we produce a lot of carbon dioxide to the air we don’t know. In nowadays ours vehicle are consume gasoline both benzene and diesel enormously‚ but recently we have new innovation of car’s engine call “hybrid”. Hybrid cars are save our energy! * Thesis statement: Hybrid cars are the best fuel economy and efficiency car in the world. II. Body Paragraph 1 (Pro1) * Topic sentence: hybrid cars are efficiency car in the world.

Car Price Differentials in the European Union Submitted By: ‘Group 4’ Jan1‚ 1993: The single European act became law among member states of EU Goal: To remove barriers to cross border trade & investment within confines of EU Benefits: Increased competition & corresponding reduction in prices Jan1‚ 1999: EU’s member states adopted Euro as common currency Benefits: Would make it easy for the European consumers to compare prices across nations leading to harmonization of prices within Euro

The electricity is used only as an intermediate energy storage medium to improve the overall efficiency of the vehicle. They therefore DO NOT need to be plugged in to recharge the battery. This cuts down on the amount of fuel needed‚ producing fewer emissions and lowering overall fuel costs. As with BEVs‚ most hybrids also use ‘regenerative braking’‚ which captures energy from braking to be put back into the battery - this improves energy efficiency and reduces brake wear. Plug in hybrid electric

I. Introduction Crash‚ boom‚ bang! In an instant‚ a car accident can change a person’s life forever. Each year‚ many unsuspecting drivers‚ passengers‚ and pedestrians are killed on the roads of the United States. The main question we ask ourselves is why? Are people killed because of high speed crashes? Did the airbags not deploy at the proper time? Were the roads in acceptable conditions? Unfortunately‚ we can not always determine the causes of all accidents‚ simply because we were not on

oppressive government‚ they hold no power in society. A Thousand Splendid Suns‚ written by Khaled Hosseini is a story of two young women‚ Laila and Mariam‚ who face and overcome many hardships and live in a country destroyed by political oppression and war. Hosseini exposes the inner strength of Afghan women through the point of view of these two women; a strength that enables them to endure difficult situations including forced marriages‚ the Taliban insurrection‚ and a lack of educational opportunities

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

How Hybrid Cars Work A hybrid car is a passenger vehicle that is driven by a hybrid engine‚ which is any engine that combines two or more sources of power‚ generally gasoline and electricity. There are two types of gasoline-electric hybrid cars; the parallel hybrid‚ and the series hybrid. Both use gasoline-electric hybrid technology‚ but in radically different ways. In a parallel hybrid car‚ a gasoline engine and an electric motor work together to move the car forward‚ while in a series hybrid

Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and
