Answer:
Tsunamis are usually triggered by earthquakes, volcanic eruptions and underwater explosions, landslides and other mass movements. Underseas earthquakes have generated nearly all the major tsunamis in history. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.
Explanation:
Answer A is correct because of the fact that tsunamis can be caused by underwater explosions
Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
Galena is an important economic mineral for lead. It's an important mineral as it serves as an ore for most of the world's lead production.
Answer:
The value of Ka
It is a weak acid
Explanation:
From the question we are told that
The concentration of
The concentration of
The concentration of
Generally the equation for the ionic dissociation of is
The equilibrium constant is mathematically represented as
Substituting values since all value of concentration are at equilibrium
Since the value of is less than 1 it show that in water it dose not completely
disassociated so it an acid that is weak
