What is the difference between force and energy? A force is any action that tends to alter the state of rest or uniform motion motion of a body. This is essentially Newton’s first Law of motion. Energy is a property of an system that is a measure of the capacity to do work. for example […]
How did you separate the components of salt water solution?
How did you separate the components of salt water solution? For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. What technique […]
What are the 3 types of wells?
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 […]
Is the Court of International Trade a federal court?
Is the Court of International Trade a federal court? The United States Court of International Trade is an Article III federal court. The Customs Court Act of 1980 replaced the former United States Customs Court with the United States Court of International Trade. The chief judge of the court is Timothy Stanceu, who was appointed […]
What is the change of state when wax melts?
Is it bad to be in peak heart rate zone?
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 […]
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 […]
