Which of the following noble gas is least Polarisable? Helium Why is argon a stable element? Nearly all of the argon in the Earth’s atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth’s crust. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding […]
Why is momentum not always conserved?
Why is momentum not always conserved? The total momentum of both objects does not change. For this reason we say that the total momentum of the interacting objects is conserved. Newton’s third law implies that the total momentum of a system of interacting objects not acted on by outside forces is conserved. Is angular momentum […]
Which of the following best describes a difference between artificial and natural selection?
Which of the following best describes a difference between artificial and natural selection? The following statement best describes the difference between artificial and natural selection: Natural selection acts without the input of humans: artificial selection requires human input. only via natural selection, genetic drift, migration, or mutation. Which best describes the role of mutations in […]
Does all water run through water heater?
Does all water run through water heater? The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home. To get to every appliance, these pipes need to run throughout […]

Are high luminosity stars rare?
Are high luminosity stars rare? The volume of space included within a distance of 5000 light-years, however, is enormous; so even though highly luminous stars are intrinsically rare, many of them are readily visible to our unaided eye. Does Chemo age your face? The study authors said a wide-ranging review of scientific evidence found that: […]
What does G pair with in DNA?
Are cathodes positive?
Are cathodes positive? The anode is the electrode where electricity moves into. The cathode is the electrode where electricity is given out or flows out of. The anode is usually the positive side. A cathode is a negative side. Is cathode positive or negative in battery? The electrode of a battery that releases electrons during […]
What periodic trend is most important for determining metal reactivity?
What periodic trend is most important for determining metal reactivity? Metallic and Non-metallic Character Within a compound, metal atoms have relatively low attraction for electrons, as indicated by their low electronegativities. By following the trend summary in the figure below, you can see that the most reactive metals would reside in the lower left portion […]
