What are the 3 types of wells? There are three types of private drinking water wells. Dug/Bored wells are holes in the ground dug by shovel or backhoe. Driven wells are constructed by driving pipe into the ground. Drilled wells are constructed by percussion or rotary-drilling machines. Does rain fill your well? While your well […]
What are the limitations of valence bond theory?
What are the limitations of valence bond theory? Limitations of Valence Bond Theory The theory assumes that electrons are localized in specific areas. It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds. No distinction between weak and strong ligands. Why MOT is preferred over VBT? molecular orbital theory […]
Why some elements are reactive?
Why some elements are reactive? The number of electrons in the outermost shell of an atom determines its reactivity. Halogens are highly reactive because they readily gain an electron to fill their outermost shell. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell. Is S or O more […]
Which statement best describes what occurs during a chemical reaction?
Which statement best describes what occurs during a chemical reaction? During a chemical reaction both the identity and the properties of a substance change. Chemical reaction between two substances occurs to form a new substance which is completely different. Therefore, it has different appearance and physical state as well as the chemical properties. Which statement […]
Is it bad to be in peak heart rate zone?
Is fuel line measured ID or OD?
Is fuel line measured ID or OD? Tubing is OD (outside diameter) and Pipe is ID (inside diameter). So the easiest way to tell the size of your fuel line, which is tubing, is to use a combination wrench. Whichever one slips over snuggly is the winner. What size is fuel line? Recommended Size, Based […]
What are the odds of getting West Nile?
What are the odds of getting West Nile? The odds of getting the most severe forms of West Nile disease are about one in 150. What are the long term side effects of West Nile virus? The most common long-term effects are depression, tremors, fatigue, memory problems, extremity weakness, word-finding difficulty and headaches. Since WNV […]
Which best describes the difference between radiation and conduction?
Which best describes the difference between radiation and conduction? Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the […]
What are 2 types of speed?
What are 2 types of speed? There are two types of speed: result-speed and task-speed. What are 3 types of speed? In general, there are three types of speed limits: absolute, presumed and basic. What are 4 types of speed limits? In California, there are four major Speed Laws: Basic, Prima Facie, Maximum, and Minimum. […]
Is there a measure of sharpness?
Is there a measure of sharpness? There is no unit of sharpness but instruments are available to measure it. Those instruments provide accurate results with high precision. What is the sharpest knife in the world? Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 […]
