Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater. According to the Professional Association of Diving Instructor (PADI)‚ a “DEEP DIVE” is considered to be anything from 18 meters (60 ft) to 30 meters (100 ft). A scuba diver moves around underwater by using swim-fins attached to the feet‚ however external propulsion can be provided by a diver propulsion vehicle. Scuba diving may be performed for a number of reasons; either for recreational purposes

Keghan Chapter 8 MULTIPLE CHOICE QUESTIONS Topic: Structure Elucidation 1. An alkene adds hydrogen in the presence of a catalyst to give 3‚4-dimethylhexane. Ozonolysis of the alkene followed by treatment with zinc and acetic acid gives a single organic product. The structure of the alkene is: CH3 A) CH3CH=C-CHCH2CH3 (cis or trans) CH3 CH3 B) CH3CH2C=CCH3 (cis or trans) CH2CH3 C) CH3 CH2=CCH2CHCH2CH3 CH3 CH2 D) CH3CH2CCHCH2CH3 CH3 CH3 E) CH3CH2CHCHCH=CH2

Properties of Different Bonds An ionic compound forms from a nonmetal and metal element. A covalent compound is formed by two non metal elements. A metallic compound is formed by two metal elements. Metallic compounds have generally high melting points‚ are loose and flexible with their electrons‚ conduct electricity well‚ and have low solubility in water. Ionic compounds are generally crystals‚ have a high melting point‚ and usually have high solubility in water and conduct electricity well when

Question 1 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation where is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation where is Planck’s constant (). Note that frequency has units of inverse seconds ()‚ which are more commonly expressed as hertz (). Part A A microwave oven operates at 2.40 . What is the wavelength

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members

Nuclear Chemistry Nuclear science is the study of sub-atomic particles and their function in various subjects. A nucleon is the collective name for the two components of the atomic nucleus: the neutron and the proton. Isotopes are any of the different forms of an element each having different mass numbers‚ which give the total number of nucleons. The major fundamentals of nuclear chemistry include radioactive decay‚ the nature of fission and fusion‚ and mass defect. The decomposition of the
