Answer:
Orbital
Explanation:
In Bohr's model, the planet model, it was thought that electrons were orbiting a nucleus just as planets are orbiting the sun. Over time, this model was proved to be inconsistent with the further findings, especially with the fact that electrons exhibited wave properties.
This lead to defining orbitals in terms of quantum mechanics. An orbital is defined as a space in which the probability of finding an electron is 95 %. Each allowed orbital has a precisely known energy, this is why we can calculate the energy needed to promote an electron to a higher orbital, as we know the difference in energies between the orbitals.
Commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.
<h3>
What are the technologies that could help reduce the damage from a tsunami?</h3>
Commonly seawalls are used for preventing damage from tsunamis. There is a network which is used for detecting the earthquake and tsunami and that network is known as Seismological network. This network helps the people to know about the earthquakes and tsunamis and reduces the damages of earthquakes and tsunamis.
The engineers also design a special type of special buoys which is also known as floating devices, these devices are placed near the coastal areas from where the tsunamis can be detected easily.
So we can conclude that commonly the sea walls are used for preventing damage from tsunami. A special type of device is also used for detecting the tsunami called floating device.

Answer:
Molar mass of Na2HPO4=141.96, of Na2HPO4. 12H2O = 358.14: so to get the same 0.4 M: 28.65/358.14*141.96 g, add water until you reach 200ml , dissolve all solid and then filter to make sterile.
