Which is older fault or intrusion? An intrusion is always younger than the rock layers around and beneath it. A fault is always younger than the rock it cuts through. The surface where new rock layers meet a much older rock surface beneath them is called an unconformity. An unconformity is a gap in the […]

Is dull a metal or nonmetal? Properties Metals Non-metals Appearance Shiny Dull State at room temperature Solid (except mercury, which is a liquid) About half are solids, about half are gases, and one (bromine) is a liquid Density High (they feel heavy for their size) Low (they feel light for their size) Strength Strong Weak […]
Does CH4 have a dipole?
Does CH4 have a dipole? The dipole moment of methane CH4 is zero. Is CH4 a dipole-dipole force? Also CH4 molecules cannot have permenant dipole-dipole attractions because each of the species bonded to the carbon is identical and CH4 has a tetrahedral shape. Therefore the strongest intermolecular forces between CH4 molecules are Van der Waals […]

What is one reason astronomers like to build large telescopes?
What is one reason astronomers like to build large telescopes? The reason astronomers keep building bigger and bigger telescopes is that celestial objects—such as planets, stars, and galaxies—send much more light to Earth than any human eye (with its tiny opening) can catch, and bigger telescopes can detect fainter objects. Which of these are the […]
What are five factors that affect the rate of a chemical reaction?
What are five factors that affect the rate of a chemical reaction? Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration […]

What is the difference between an open and a closed feedwater heater FWH )?
What is the difference between an open and a closed feedwater heater FWH )? There are actually two main types of feedwater heaters. If the steam mixes with the compressed water from the pump, it is an open feedwater heater. If the steam does not mix with the compressed water from the pump, it is […]
