Do Isotopes have the same atomic mass? Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus. How do you tell if an atom is an isotope? Look up at […]

What liquids dont contain water? Bromine and mercury are liquids are room temperature and, when pure, have no water in them. Pure solvents and compounds (other than water) have no water. Gasoline does not (or should not) have water in it, however, ethanol, which can be in gas, absorbs and holds water. What is a […]

Which harmonics are missing in closed organ pipe? If both the ends of pipe is open it is called as Open organ pipe like Flute. A closed organ pipe has an antinode at the open end and node at the closed end. “In closed end organ pipe, even number harmonics are absent.” Why do closed […]

At what joint does eversion and inversion occur? subtalar joint What muscles do inversion? There are two muscles that produce inversion, tibialis anterior, which we’ve seen already, and tibialis posterior. The other muscle that can act as a foot invertor is tibialis anterior, which inserts so close to tibialis posterior that it has almost the […]

Which are examples of perfectly inelastic collisions quizlet? Examples of perfectly inelastic collisions include: Person catching a ball, meteorite hitting earth, two clay balls colliding. Examples of inelastic collisions include: Two cars colliding, changing form, and moving separately after the collision. What is the difference between an inelastic and perfectly inelastic collision? An inelastic collision, […]

What is the most common star system? The most common of the multiple star systems are binary stars, systems of only two stars together. Is a trinary star system possible? It hardly seems possible, but researchers have detected a planet in apparently stable orbit within a three star system — a configuration now known as […]

What are the negative effects of generating electricity? Emissions of greenhouse gases and other air pollutants, especially when a fuel is burned. Use of water resources to produce steam, provide cooling, and serve other functions. Discharges of pollution into water bodies, including thermal pollution (water that is hotter than the original temperature of the water […]

Are water parks full of germs? Basically, water parks are a breeding ground for all things bacteria, including skin infections, athlete’s foot, and beyond. Why do pools smell? Pool smell is due, not to chlorine, but to chloramines, chemical compounds that build up in pool water when it is improperly treated. Chloramines result from the […]

Which elements are too reactive in nature? Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form. The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have […]
