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

ago today I was going to watching Kurt referee his very first high school basketball game. I was so excited and so proud of him. I had no clue three years ago how much reffing would become a part of our life. Reffing is life in our household. Honestly‚ reffing takes up about 9 months of our life. From November-March is basketball season. May-July are camps where he is away on the weekends. October is when he has all the clinics and scrimmages. Basically he is off April‚ August and September

If one just pulls out a minute from the trap of economic integration and gaze around‚ it will immediately come to notice how engineering makes a difference in life. We live in a world where globalization is an important force shaping our future and we are so interested in technological advances that drive the economic engines of the world‚ but as stated by the IUPAP‚ what provides all the basic knowledge and research is simply the field of physics with all its branches of engineering. Would today’s

century BC Aristotle‚ practical as ever in his determination to get things worked out in detail‚ proposes a new theory to explain how the four elements of Empedocles and the atoms of Democritus produce the wide range of substances apprehended by our senses. He declares the existence of only four elements: fire‚ air‚ water and earth. All matter is made up of these four elements and matter had four properties: hot‚ cold‚ dry and wet. Greek science in Alexandria: from the 3rd century BC
