The answer is the second option. The given conversion from L to dm3 is actually confusing. Just remember that 1 L = 1000 cm3.
Simply, multiply 2.6 by 1000 and we get 2600 cm. Converting this to scientific notation, we get the answer:
2.6 x 10^3 cm3
It’s fluorine it has a big jump from the 6th to 7th ionisation energy.
It’s electronic configuration is 1s2 2s2 2p5 as it has 9 electrons and 7 electrons in outermost shell.
Therefore it’s in group 7, as after the 7 electrons are removed, the 8th electron is removed from a quantum shell closer to the nucleus.
This results in greater ionisation energy due to stronger electrostatic forces of attraction between positively charge nuclei and electrons ( + shorter distance)
Answer:
evaporation
Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water
Explanation:
Answer:
When objects from space (meteoroids, space shuttles) enter the atmosphere, they start heating up in the mesosphere.
Explanation:
It will get hotter, because the molecules create heat when they move around just like us when we run.
