This molecule is formed between a not very electronegative metal and a very electronegative nonmetal which means it should be an ionic compound which would mean that it would have the name of potassium oxide.
look up the naming rules for ionic compounds. I would explain it here but I don't know how to explain naming the anion part of the molecule other than it ends in ide since it is a monoatomic anion which is why oxide is in the name instead of oxygen.
I hope this helps. Let me know if anything is unclear or needs more explanation.
Insulators maintain temperatures better
Because the gravity near the earths crust/surface is greater than once in orbit it doesnt need any fuel because the earths gravatitional pul is keeping it in orbit just like it keeps the moon it orbit around it and the sun keeps the planets in its orbit
Hope This Helps!
Answer:
efficiency of a machine is less than 100% because some part is energy is utilized to overcome some opposing forces like friction which is wasted as heat ,sound energy etc
Explanation:
Answer:
Modern telescopes are capable of seeing bright galaxies up to about 10000 millions light years away
Explanation:
A telescope is a tool that astronomers use to see faraway objects. Most telescopes work by using curved mirrors to gather and focus light from the night sky. The bigger the mirrors or lenses, the more light the telescope can gather.
Modern telescopes gather information from the electromagnetic spectrum far beyond the range of visible light.
The farthest bright galaxies, that the modern telescope is capable of seeing is 10000 millions light years away.
