Answer: Infrasound because sound waves travel easily through water to accessible buoys.
Explanation: its installation: underwater microphones hung from buoys near a volcano. how it works: senses low-frequency sound waves near a volcano. Since in its installation it specifies that it has UNDERWATER microphones and the question asks in predicting an eruption from an UNDERSEA volcano, that makes perfect sense.

Answer: To answer your question of what is true of a lewis base, it is true that a lewis base donates electron pairs.
Explanation: A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
<u>Answer:</u> The concentration of KOH solution is 1.215 M
<u>Explanation:</u>
For the given chemical equation:

To calculate the concentration of base, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH.
We are given:

Putting values in above equation, we get:

Hence, the concentration of KOH solution is 1.215 M
Hello,
As the speed increases the Energy does not change. This is because of Law of conservation of mass. Energy can be created or destroyed.
Thus the energy levels will stay the same but the form in which the energy is presented may change.
Hope this helps! Have a great day.
