What does fully ionized mean? When referred to an atom, “fully ionized” means that there are no bound electrons left, resulting in a bare nucleus. Regular stars largely contain hydrogen and helium that are fully ionized into protons (H+) and alpha-particles (He2+). Which element would have the highest ionization energy? helium What is Fluorines ionization […]

On which day are your answering stats reset? Stats including CF score get reset on the 1st of every month (at 12:30 PM). This is to give you a better clarification on how many questions you have solved and skipped in a month. How many questions can you skip on Chegg question and answers? How […]

How do you find initial kinetic energy? Kinetic Energy and Work The kinetic energy of an object is defined as 2 KE = 1/2 * m * v. The kinetic energy of an object depends on its velocity. We can this combination of force and distance work, so KE(final) – KE(initial) = Work done on […]

What is the darkest phase of the moon? The moment a thin sliver of the Moon becomes visible after New Moon is the beginning of the first intermediate phase, the Waxing Crescent Moon. In the past, this used to be called New Moon while the darkest phase was called Dark Moon. How long does the […]

Is a survey a secondary source?

Is a type of construction where the main load-bearing? Explanation; Suspension is a type of construction where the main load-bearing elements are hung from suspension cables that are then suspended from vertical supports anchored into the ground or a riverbed. How is a suspension construction made where is it most commonly used? How is a […]

How do you tell if the tide is coming in or out? You can tell if the tide is coming in or out by reading a local tide table since they list the predicted times that the tide will be highest and lowest. In the time that the tide shifts from its lowest point to […]

What will happen to the pressure of a contained gas if its temperature is lowered? How does a decrease in temperature affect the pressure of a contained gas? The pressure decreases because the kinetic energy decreases with the temperature and slower moving particles impact the walls of a contain with less energy. Which three factors […]

What are visible light examples? For example, the sun produces visible light. Incandescent light bulbs, fluorescent, and neon lights are other examples of visible light that we may see on a regular basis. Visible light is probably the most important of all electromagnetic waves for most of us. What color is the presence of all […]

What tests can be done to identify an unknown substance? How Do We Approach an Unknown Substance Gas Chromatography (GC) Gas Chromatography Mass Spectroscopy (GC-MS) Ion Chromatography (IC) High Performance Liquid Chromatography (HPLC) Dispersive Raman Spectroscopy. Fourier Transfer Infrared Spectroscopy (FTIR) What is the unknown solution? A titration is a technique where a solution of […]
