Explanation:
The speed of seismic waves is affected by the density of the underlying rock.
Seismic waves are elastic waves that transmits elastic energy from one point to the other.
These waves generally produced during an earthquake.
- The higher the density of rock bodies, the faster the wave travels.
- Rocks that are well packed with little to no void have a higher seismic velocity.
- Where density of rock is low, the speed is also low
The answer is: lose electrons and form positive ions.
Most metals have strong metallic bond, because of strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
For example, magnesium has atomic number 12, which means it has 12 protons and 12 electrons. It lost two electrons to form magnesium cation (Mg²⁺) with stable electron configuration like closest noble gas neon (Ne) with 10 electrons.
Electron configuration of magnesium ion: ₁₂Mg²⁺ 1s² 2s² 2p⁶.
Ummm I think it is C. ( not sure)
Answer:
The Gwichʼin or Kutchin are an Athabaskan-speaking First Nations people of Canada and an Alaska Native people. They live in the northwestern part of North
Explanation:
Answer:
The reaction is endothermic
Part A: Yes because there is an immediate reaction of bubbling vigorously.
Part B: It releases energy because when the compounds are added together they are immediately releasing it by bubbling and turning cold.
Part C: Yes because the liquids inside when combined give off coldness that makes the liquid temperature decrease to use this chemical reaction could definitely be used to keep something cold
