Laboratory Report The title of the lab that we completed in class was The Law of Conservation of Matter. The purpose of this lab was to find out if matter can be created or destroyed in a chemical reaction. Dalton came up with the atomic theory‚ which included the law of conservation of matter. His theory was that matter cannot be created or destroyed and that chemical reactions only rearrange the way that atoms are combined; the atoms themselves don’t change. The procedure went like this

Title: Law of Conservation of Mass Purpose: The purpose of the Law of conservation of Mass lab is for me to attempt to verify the Law of Conservation of Mass. Procedure: Acid Base Neutralization 1. Using 2 modified‚ beral pipettes fill pipet an about 1/5 full of white vinegar and pipette B about 1/5 full of 1.0 M NaOh (sodium hydroxide). 2. Place the 2 Pipets on the beam balance and read and record the total mass of the 2 pipets. 3. Carefully telescope the stem of

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

The 1956 Grand Canyon Midair Collision By Bryan Smith Air accidents have been a common occurrence since the beginning of aviation. In the early years they were viewed as an inevitability and even accepted as a consequence of man’s quest to conquer the skies. Though there have always been attempts to prevent these accidents‚ not every possibility can be predicted‚ let alone planned for or prevented. Thus‚ in many ways‚ the advancement of aviation has mostly been reactionary‚ sometimes necessitating major events

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

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

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.<br><br>Torque is the angular "version" of force. The units for torque are
