For this assignment‚ you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is

I placed out two of my solo cups on the counter 2. Then I put 1 cup of room temperature water into each cup. 3. Then put one Alka-Seltzer Tablet in one cup and time it until it dissolves completely. 4. In the second cup I put in a crushed up Alka- Seltzer tablet and timed it until it

iodide is formed. 3.) Collision Theory Illustration 1.2 -The following hypothetical chemical reaction illustrates the collision of the molecules of two gases‚ A2 and B2‚ to form another compound of AB. - Furthermore‚ the colliding species must be oriented in a manner favorable to the necessary rearrangement of atoms and electrons. Thus‚ according to the collision theory‚ the rate at which a chemical reaction proceeds is equal to the frequency of effective collisions. Because atomic or molecular

1) Introduction This Lab is about conservation of momentum. It is to investigate the difference of momentum before and after collisions. Using the photo gates record the velocity of each cart‚ comparing momentum and kinetic energy to find the law. The experimental apparatus are two red carts in approximately same weight and a gold cart in lower weight than the red ones‚ a stable air track (blow a constant stream of air out through numerous tiny holes) with low friction and two photo gates. 2) Project

*CHEMICAL KINETICS Collision theory and rates of reaction *One of the main considerations when examining chemical reaction is whether it will take place fast enough for it to be useful. *In other words‚ there’s no point carrying out a reaction if it takes 150 years to form the product! *Many chemical reactions occur very quickly. *Studying Reaction Rates *Defined as the change in concentration of reactants of products per unit time. *Units: mol dm¯³ s¯¹ *Rate of Reaction * ‚ the

Physics G Unit 6 – Momentum Internet Lab – Momentum and Collisions Name: Date: Period: Website: http://phet.colorado.edu/ Play with the Sims Physics Motion Collision Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kg·m/s. During a collision objects transfer momentum to each other‚ resulting in different motions than before the collision. In this activity you will study

During a car crash‚ there are three different collisions that occur. The first one is the collision of the car and the opposing object‚ the second is the human inside the car and the car itself. The final collision is the ones that occur within the human body itself. BRAIN: The human brain is protected by the cranial cavity or the skull. The brain is suspended in a substance called the cerebral spinal fluid‚ which is denser than the skull itself. In a collision‚ the brain and cerebral spinal fluid begin

but interrelated activities‚ functions and process that are directed at attracting‚ developing and maintaining or disposing firms’ human resources (lado & Wilson 1994). Banks‚ like any other firm‚ need to transform inputs into outputs at an efficient rate in order to maximize profitability and to survive under competitive conditions. Therefore‚ if a bank is using more resource in the process than is technically required‚ it will be operating below the “frontier” of efficiency. Chief among the resources
