Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction

Title: PROP0332 Evaluation of the Gas Law Constant Abstract: The result of the change in volume was approximately 22 CC or 0.00084 mol. This translates into the average for the R constant being 83.8L*atm/K*mol. The four determinations ensured that the results were accurate because more than one trial helps somewhat prevent error. Approximately 0.20g of the Mg ribbon was used for these determinations. Introduction: 1. Theory If the temperature of a gas sample was held constant‚ its volume

The Physics of Basketball Brittney LeBlanc Physics 122 Physics comes into play throughout our lives‚ in absolutely everything we do‚ especially in sports such as basketball. Although you do not need to be a physician to become a basketball player‚ if you understand the basic physics of basketball‚ it can be very beneficial to your game. Specifically‚ understanding the physics behind shooting‚ passing‚ and dribbling the basketball. A Canadian named‚ Dr. James Naismith‚ was instructed to create an

typically bring about rotary motion. The Laws of Motion form the foundation of dynamics. First Law of Motion An object will remain at rest or continue to move at a constant velocity unless acted upon by an external force. F = net force If F = 0 ⇒ v = constant Third Law of Motion For every action there is an equal but opposite reaction. These two forces (action & reaction) act on different bodies. Freaction Faction = − Freaction Faction Second Law of Motion When a net external force acts on

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

The Jewish Scripture starts right at the beginning of time itself‚ where God created the universe‚ and only then did he create the earth (Genesis 1). Right from the beginning God has had an intimate connection between God and the world‚ and this connection is believed to continue throughout time. From the moment god created humanity (Gen. 1:26)‚ we were created for the one purpose to protect the earth. But it is in the story of Noah that we perhaps truly learn about the role that God had created

Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

Newton’s Second Law (Predicting Accelerations) Abstract: The purpose of this experiment is to study the Newton’s second law and the behavior of objects for which all forces are not balanced. In this experiment‚ a small mass m will be connected to the dynamics cart by a string. The string will pass over a pulley at the table’s edge so that as the mass falls the cart will be accelerated over the table’s force. The cart will be released from rest and allowed to accelerate over a distance. Using a
