To determine the pH of the solution. All you would have to do is use the equation:
pH = -log(H3O^+)
pH = - log(0.0007)
pH = 3.15.
Note that H+ and H3O+ are the same, it is more accurate to say H3O+ because of how the H2O molecules become after receiving the additional proton.
As you get higher the atmospheric pressure lowers. The pressure in the packet of crisps has the pressure at which it has been closed (pressure at the surface of the earth). This means that the air molecules in the packet press harder outside than the air molecules in the atmosphere press on the packet.
It changes because when the 2 tectonic plates collide they form mountains and volcanoes.
Continental drift causes tectonic plates to either "pull apart" or "crash" into each other.
Plates that crash into each other either form mountains, or when one slides under the other (a subduction zone) volcanoes from.
Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.
