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? 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 […]

Why are chloroplasts green?
Why are chloroplasts green? Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Where is glucose found? Glucose ― […]
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 […]
What are five ways that the order of rock layers can be disturbed?
What are five ways that the order of rock layers can be disturbed? Folding, tilting, faults, intrusions, and unconformities all disturb rock layers. Sometimes, a single rock body may have been disturbed many times. Geologists must use their knowledge of the things that disturb rock layers to piece together the Earth’s history. What rocks are […]
