Experiment #9 – Identification of Aldehydes and Ketones Introduction Aldehydes and ketones share the carbonyl functional group which features carbon doubly bonded to oxygen. In the case of ketones there are two carbon atoms bonded to the carbonyl carbon and no hydrogens. In the case of aldehydes there is at least one hydrogen bonded to the carbonyl carbon; the other attachment may be to a carbon or a hydrogen. In all cases the carbon(s) that are attached to the carbonyl group may be aliphatic (not

AP Physics Laboratory Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine

matter‚ including the fourth and fifth states: plasma and the Bose-Einstein Condensate‚ or BEC. The plasma and Bose-Einstein Condensate states of matter‚ while having some similarities‚ are two completely different forms of matter and connect with the Kinetic Molecular Theory in differing ways. Plasma is the fourth state of matter. It’s a fluid‚ gas-like substance that consists of a mixture of free electrons‚ neutral atoms‚ and charged ions. It is made up of both positively and negatively charged particles

AP Chemistry Final Exam Review ESSAY. Write your answer in the space provided or on a separate sheet of paper. 1) Explain the difference between a qualitative and a quantitative measurement. Provide examples to illustrate this difference. Answer: A qualitative measurement is a measurement that gives descriptive‚ nonnumeric results; a quantitative measurement is a measurement that gives definite‚ usually numeric results. "The rock is heavy" would be a qualitative measurement. "The rock weighs 110

CHAPTER I THE PROBLEM AND ITS BACKGROUND Background of the study Herbal medicines have been part of the ingenious way of living in the society since the earlier times. Primitive men have been using this kind of medicine as the primary method of medication without undergoing different industrial processes. Herbal medicines have really come a long journey way back to the ancient times of Herbalism. One of the considered pioneers in Herbal medical field was Imhotep‚ a priest-physician of the ancient

Rides and rollercoasters Many theme park rides use the transfer of gravitational potential energy to kinetic energy and kinetic energy to gravitational potential energy. A rollercoaster A rollercoaster car converts GPE to KE when it rolls down the track As the pirate ship falls‚ GPE is transferred into KE. At the bottom of the swing it’s travelling at its highest speed. As it swings back up the other side it slows down as its KE is transferred back into GPE. Rollercoasters use these energy

consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how to make predictions about reactivity based on the structure of the reactants and intermediates. We begin by reviewing the principles of thermodynamics and kinetics‚ which provide the basis for understanding the relationship of structure to stability and

Collisions in 2-Dimensions (Glancing Collisions) Inelastic Collisions Collisions in which kinetic energy is not conserved. Initial kinetic energy is transformed into other types of energy (thermal‚ potential etc.) Total final kinetic energy is less than the total initial kinetic energy. If two objects stick together as a result of the collision‚ the collisions is inelastic. Even though the kinetic energy is not conserved‚ the total energy is conserved. 1-Dimensional Inelastic Collisions
